Capsule Review: Logitech MK850 Performance Wireless Keyboard and Mouse Combo

We have been reviewing Logitech’s multi-device wireless input peripherals for a few years now. The Logitech K480 was launched in 2014, and the Logitech K780 and M720 keyboard and mouse were launched last year. The K780 and M720 Triathlon were separate products. The success of these input peripherals has prompted Logitech to introduce the MK850 Performance combo – a full-length multi-device wireless keyboard along with the wireless M720 Triathlon mouse. The combo is made more powerful by the DuoLink feature – using the keyboard to alter the functionality of the mouse buttons and gestures.

The Logitech MK850 Performance combo comes with a single Unifying USB receiver. Logitech also bundles a USB extender for use-cases where the placement of the spare USB port in the PC might result in spotty wireless performance. The combo can be paired with up to three different host devices and easily switch between them. The hosts can be Android, iOS, Mac or Windows devices, and the keys in the keyboard get automatically re-mapped depending on the host OS. Both the mouse and the keyboard have explicit on/off buttons in order to conserve battery life. The keyboard needs 2xAAA batteries, while the mouse needs a single AA battery. Logitech claims battery life of two years for the mouse and three years for the keyboard.

We had talked about how the K780 keyboard addressed the shortcomings of the K480 keyboard. The keyboard component of the MK850 adds a number of interesting features.

• Ergonomic contour with a raised profile in the middle, suitable for extended duration usage
• Full-sized keyboard (101 keys) with explicit number pad and full-sized arrow keys.
• Cushioned palm rest along the lower side of the keyboard for comfortable extended duration usage
• Availability of multiple tilt angles for the keyboard (0, 4, or 8 degrees)
• Better typing experience compared to the K480 and K780
• Ability to use the Fn key to enhance the combo mouse functionality

Users of the K480 and K780 have appreciated the ability to use the cradle to keep their smartphones in an accessible location while using their computers. The MK850’s keyboard, however, doesn’t have a cradle for mobile devices.

Hardware-wise, the mouse component of the MK850 is the M720 Triathlon (the sticker on the back of the mouse even has the M720 Triathlon label). The mouse is also the component in the package with a compartment to store the Unifying receiver. As part of the MK850 combo, the differences boil down to the DuoLink feature controlled by the Logitech Options software.

The Logitech Options Software

The Unifying receiver bundled with the package is obviously configured to keep both devices active simultaneously. Installing the Logitech Options software presents both devices along with the battery levels and connection method (Unifying receiver or Bluetooth) at a single glance.

The options available for the mouse (standalone) are an exact replica of what we saw in the M720 Triathlon review. Out of the 8 buttons in the mouse, two (the one behind the scrollwheel that controls the rate at which it moves, and the one that switches the host device to which the mouse is paired) can’t be remapped. Everything else can be configured using the Options software.

The left and right buttons can be swapped. The pointer speed can be finely adjusted and the scrollwheel direction can also be swapped. The mouse also has a gesture button below the three raised buttons on the left side. The scrollwheel can be swayed right or left for horizontal scrolling (on mobile devices, that acts similar to swiping right or left on the touchscreen). Along with the device change button, we also have the Forward and Back buttons on the left. The scrollwheel can itself act as a middle mouse button. All of these can be mapped to one of a variety of Windows actions.

Activating the Options software when the K850 Performance keyboard as well as the M720 Triathlon mouse are connected provides users with the ability to configure the DuoLink features. The option panels associated with the mouse have a ‘Default’ and a ‘Fn’ mode, with the latter configuration intended for activation by pressing the Fn key on the keyboard along with the relevant mouse event.

Gallery: Logitech Options – DuoLink and Keyboard Options

The K850 Performance’s options include the ability to keep the keyboard always in the Windows layout and the option to use the F1-F12 keys as standard function keys (without using the Fn. key qualifier). The configurable keys include the Home button, F1 through F4, F11, and F12. They can be mapped to a variety of Windows functions / programs such as closing windows, Cortana, Calculator etc.

Concluding Remarks

The MK850 Performance wireless keyboard and mouse combo is an important addition to the set of multi-device I/O peripherals from Logitech. They work as advertised, and there is really not much to complain about, except for the lack of a cradle in the keyboard. As mentioned earlier, the K850 Performance keyboard is a huge improvement over the K480 and K780. Evaluation of keyboards and mice targeted towards day-to-day / casual usage is an inherently subjective exercise. In the table below, we compare the specifications of the MK850 Performance combo with some of the other keyboard / mice combos that we have evaluated with a similar approach before. Some subjective scores have also been provided.

While it is difficult to find scope for improvement in the M720 Triathlon, the K850 Performance keyboard’s appeal can be enhanced by the addition of a cradle to the design, as well as making the palm rest detachable. As a combo, the whole is more than the sum of parts, thanks to the DuoLink features.

The MK850 Performance combo is priced at $99.99. Given that the M720 Triathlon mouse had a MSRP of $70 at launch, the pricing of the MK850 Performance combo seems pretty reasonable. Logitech has primarily focused on the niche mobile device input peripheral market with their multi-device Bluetooth / wireless models. The design of the K850 Performance keyboard makes it suitable for heavy office use. This will help Logitech address a wider market with the MK850 Performance wireless keyboard and mouse combo.

Logitech Multi-Device K780 Keyboard and M720 Triathlon Mouse Review

Logitech introduced an innovative multi-device Bluetooth keyboard, the Multi-Device K480, back in 2014. The K480 could be configured for use with up to three different devices, and definitely stood out in the crowded I/O peripherals market. Our wish-list for a follow-up product included an integrated trackball or touchpad and ability to use such multi-device peripherals with a wider range of PCs (not just the ones with Bluetooth capabilities).

This year, Logitech has expanded their multi-device lineup with two new products:

• K780 Multi-Device Keyboard
• M720 Triathlon Multi-Device Mouse

Both products retain the important characteristics of the K480. They can be paired with up to three different host devices and easily switch between them. The hosts can be Android, iOS, Mac or Windows devices, and the keys in the keyboard get automatically re-mapped depending on the host OS. Similar to the K480, the K780 has Mac / iOS inputs printed in grey on the keyboard. Both the mouse and the keyboard have explicit on/off buttons in order to conserve battery life.

The two products together address many of the shortcomings of the K480 from 2014. The important features / changes are summarized in the list below.

• Consumers can use either Bluetooth or a 2.4GHz RF Unifying Receiver (included with both products) to communicate with the host device
• A dedicated number pad is present in the K780 (96 keys), but, not in the K480 (79 keys)
• The device-change mechanism for the keyboard has been altered. Instead of a rotary dial (used in the K480), the K780 uses multiplexed function keys for the same purpose
• The wider K780 keyboard allows for compatibility with more devices (including the iPad Pro in portrait mode) when it comes to placement in the cradle at the top of the unit. The K780 is also heavier and more sturdy compared to the K480.
• The keys in the K780 are easier to type on and provide a better usage experience compared to the ones in the K480.
• The mouse contains buttons and gesture support that make it ideal for use with tablets as well as PCs.

The Logitech Options and Unifying Receiver Software

The addition of a USB receiver to both units indicates that Logitech is targeting the new devices towards PCs also. The K780 and M720 Triathlon are sold separately. Both of them come with their own Unifying Receivers. For use-cases that don’t involve the USB receiver, both units have compartments to safely stow them away.

In our review process, we first connected the M720 Triathlon to a PC with its USB receiver. After installing the Logitech Unifying Software, we were also able to pair the K780 without using its USB receiver.

The Logitech Options software enables users to configure / alter the behavior of the configurable keys of all the attached compatible Logitech devices. The Unifying Receiver program can also be triggered from within this interface. The battery status of the devices can also be viewed through this program.

The K780 options include the ability to keep the keyboard always in the Windows layout and the option to use the F1-F12 keys as standard function keys (without using the Fn. key qualifier). The configurable keys include the Home button (F4), Right Click (F5), Back (F6) and the Search button (next to F12). They can be mapped to a variety of Windows functions / programs such as closing windows, Cortana, Calculator etc.

The M720 Triathlon is marketed as a 8-button device. Two of them (the one behind the scrollwheel that controls the rate at which it moves, and the one that switches the host device to which the mouse is paired) can’t be remapped. Everything else can be configured using the Options software.

The left and right buttons can be swapped. The pointer speed can be finely adjusted and the scrollwheel direction can also be swapped. The mouse also has a gesture button below the three raised buttons on the left side. The scrollwheel can be swayed right or left for horizontal scrolling (on mobile devices, that acts similar to swiping right or left on the touchscreen). Along with the device change button, we also have the Forward and Back buttons on the left. The scrollwheel can itself act as a middle mouse button. All of these can be mapped to one of a variety of Windows actions (same as the list available for the K780).

Concluding Remarks

The Logitech K780 and M720 Triathlon are a great addition to the set of multi-device I/O peripherals from Logitech. They work as advertised, and there is really not much to complain about. As mentioned earlier, the keys of the K780 are a definite improvement over the K480. Evaluation of keyboards and mice targeted towards day-to-day / casual usage is an inherently subjective exercise. In the table below, we compare the specifications of the K780 / M720 Triathlon with some of the other keyboard / mice combos that we have evaluated with a similar approach before. Some subjective scores have also been provided.

While it is difficult to find scope for improvement in the M720 Triathlon, the K780 can be made a little more attractive with full-height arrow keys (that would go well with the PC use-case).

The K780 multi-device keyboard is priced at $79.99 and the M720 Triathlon mouse is priced at $69.99. The K480 was a Bluetooth keyboard that fulfilled a niche market need. With the new multi-device models, Logitech is hoping to service that market with products that are better suited for the allied use-cases, while retaining similar price points.
