What we can tell you
A keyboard with a touchpad built into the right-hand side, meant for a sofa and a television rather than a desk. That is the whole design and it explains the layout, the size and the absence of everything else. It runs on a 2.4 GHz receiver with a vendor battery figure of well over a year. Beyond the retailer listing there is little published detail, so several specification rows here are empty.
What the specifications favour
- Integrated touchpad, so no separate mouse is needed
- A long vendor-quoted battery life on a receiver connection
- Spill resistance claimed
What to check before you buy
- Rubber-dome keys with no backlight
- Little is published about it, so several specification rows are empty
- No Bluetooth: the receiver has to stay plugged in
