I have my notebook connected to the tv, and before purchasing this device, I would have to get up to type or use my wireless mouse to type with windows on-screen keyboard. Now, no more getting up, and no need for a separate mouse and keyboard. The device is compact, but yet not too small or big. I'd say it's just perfectly sized. There's a rechargeable battery, which lasts pretty long. The box says the battery will last a month, and I think it's fairly accurate. The only thing I can really fault is the slightly high price. However, the product is in a fairly new category, which I would consider to be an early consumer adopter category, so the price is fair at this point in time. I'd recommend this product for anyone that has a computer or similar device connected to a tv, and doesn't want to have to get up to type or move the cursor on the screen. Also, built-in is a laser pointer, which may come in handy for presentations. This product has really helped my situation, and let me just be able to sit back and relax. My laptop has essentially just become a hub, that I control through this device. Lastly, I actually typed this whole review on this product's keyboard! Fantastic!
