I bought this product to make an atmosphere on a ceiling. The product makes the service that is requested. It would be useful to specify that the tape has a double face that can stick it on a wall. BUT the power supply is too low to ensure maximum power and switches to safety. So he cuts. It must unplug it and wait a bit as the security is disabled. Then reconnect by selecting another program, or it crashes again (memorizing of last cycle). It is a pity that such a product is sloppy on such a single component that diet !! Aside from that the product seems to meet the need.
