Bests & Worsts Reviews from Amazon

Extremely useful device but you need to use lithium batteries in the remote. I set it up originally with alkaline ( brand new major brand) and found the remote was losing synch with the use. This is the same problem described by a number of other review. Then I switched to lithium and immediately everything work ok and it hasn't lost synch once. With the remote working it is a great device. I did find it much cheaper at Sam's Club.
