Pros: Solid little keyboard. No issues performance issues at all. Own two, have one hooked up to my PS3 other on my computer. Buttons still all respond perfectly 6 years later.
Cons: Backspace is smaller than normal keyboards, that's not the con... the backspace key shares space with the home key and I had to remove the home key because I kept hitting it when attempting to backspace. Now, with the home key removed, con fixed.
Summary: I received the Adesso AKB-901 USB mini keyboard before delivery date. Easy to use. I just plugged it in my desktop windows 8.1. I used the mini keyboard with my HP laptop as a backup too. Had the keyboard for around a week. No problems, except there is no numerical keypad.
Pros: Compact, portable, and reasonably durable. It's got full-size keys, and it hasn't dropped or badly re-positioned any of them in the name of size.
Cons: The NumLock key controls whether the right-hand side of the keyboard is letters or numbers. Since most computers start up with NumLock on, you need to remember to turn it off before you start typing.
Summary: The keyboard is pretty solid and works perfectly, it is a nice compact size and great for tablet use (for those that have USB connectors like my ViewSonic Gtab). I would highly recommend this to anyone looking for something small and well built which should last.
Summary: The keyboard layout has some common keys such as delete in unusual places. But then I bought this for use together with an HTPC, so small footprint is the highest priority, I can live with the weird layout since it's used very infrequently.
Summary: Great product. Using it now, exactly what I needed for cheap. :) My laptop's keyboard fried, so this is a good substitute and I'd recommend it for small laptops and what now in similar situations.
Summary: I have a lap top that the keyboard was not working. After using a standard keyboard which was very clumsy I was able to buy the mini one, put it on top of the lap top keyboard and presto back in business.
