"A product that you will be very happy with"4.5 starson by Big-Mike.net
Pros: Very long battery life, great bluetooth distance, easy setup
Cons: sometimes it lags, problem if you have to reinstall OS
Summary: Out of the box this product is ready to setup. Simply put in batteries, and setup new bluetooth device. No software is needed.
The first and most important thing is that the battery like is great. I've been using this thing for 4+ months and the batteries are still about 75% full. Keep in mind I due a very large amount of typing / coding.
You can get great distance away from the computer (probably 33ft plus) so you can use the keyboard as a remote from accross the room.
Performance is great. Operates at same level as corded keyboard. Only complaint is the key input sometimes lags. example:"I'm tying 'review.' Sometimes it will show on screen as 'erview,' or worse due to lag. Other then that you will have a problem if you need to reinstall your OS as bluetooth keyboard won't be recognized so make sure you have a backup corded keyboard available.
Overall I believe you will be very happy with this keyboard. It is well worth the price.
