by Aladain from The Woodlands, Texas on May 21, 2012
I installed this product according to the Manufacturer's instructions and used good wiring practices. The products - both the switch and the ACR (Automatic charging Relay) - worked exactly as advirtised. Both seem to be high quality devices. I am highly satisfied with this purchase.
