I have been using various models of C-TEK chargers for several years. I have never had any problems with any of these products. I saw this product a while ago and finally decided to order it when I opened my Revain Prime account. I hooked it up to my car and installed a small plate in a hole in the dashboard of my Chevy Express van. It works as intended as I have a 3000w pure sine wave inverter installed and using it without the charger or motor running sometimes drains the battery. The only thing I don't know is flashing colors. I assumed the status lights were on all the time. The manual says nothing about this. I will contact C-TEK to find out. I will buy this item without hesitation. It acts as a great little battery level indicator and you can just plug the charger straight into the opening port on it which has a rubber cap.
