Rated 1 out of 5 by RWP very poor product
Packed up after 3 months despite changing batteries and checking all wiring with an electrical circuit meter. It worked on its side for a short while then packed up altogether.

Very difficult to open. Poor instructions and misleading info. Can use battery or adaptor but needs to be wired differently for each so not easily interchangable.
