Review on Bluetooth Cimetech Wireless Multi Function Extensions by Liz Smith

I bought this for office finance as my laptop didn't come with a 10 key keyboard although I have discussed this after reading past reviews. Since I only use it for homework for a short time, I take out the battery when I'm not using it and simply store all the components in a zipped pouch. I've been using it like this for a few weeks now and am still working on the first battery I put in. This particular 10 button pad might not work for those who need to use it frequently, but since I only need it for this class and for short periods of time, it works for me.
