As some others have suggested here I highly recommend checking out the textblade. Not only do I think the design is better but your money is also going to a better home rather than to a large corporate that has a dubious reputation at the best of times.
1. Does out use standard HID or something custom? Any keyboard that requires installation of a specific app or driver has a dubious future ( two now-useless Freedom Bluetooth keyboards on many cupboard testify )
2. Their website is frankly terrible. First, a pop-up that tells me to use Chrome, Safari or Firefox and renders a blank page ( this is Android Firefox ). Hack around that and it then INSISTS that I rotate my phone horizontally before showing me any content! Immediately paints a negative image of this organization.
