(around £12.94). Surprisingly, reviews on Gearbest look pretty good!
Of course my first assumption was that this is just a carbon copy of the infamously awful Linx Origami Keyboard - but apparently not, according to that HUKD thread? Post #10 here
Keys didn't miss a beat, however my touch type ability with the keyboard was a little diminished, this is due to the key size and spacing. As the keyboard is smaller than my laptop keyboard (which I am at most evenings) and my office keyboard (which I am on most of the day). My fingers naturally hover over the keys at a wider positioning than the keyboard on this. No other 10 inch keyboard would be any better as you only have so much width. The touchpad and 'tap to click' feels fine, not too responsive, but not too weak either, however the touchpad buttons do feel a bit cheap. I also found (and this may be specific to my tablet or the Linx 10 in general), when I switch the tablet on from 'full off' with it docked and set up, the keyboard and mouse are non-functional, lift the tablet and reset it after it has booted and it sees the keyboard and touchpad and all works fine.
Also to check against Gordon's comment I tried left Ctrl out and it seemed to work fine as did the left shift (being my go to when typing anyway), either Gordon got a different model or a faulty one. There may be more faulty ones out there too, I haven't read about any particularly high failure rate on these but who knows? (Just saying these are coming from China, that is always a risk I guess).
One thing that may put some prospective buyers off is that it is US layout.
Worth a punt, going to see how it goes.
