Very happy with product and price
Easy to install and seems to charge well. Would like to use the Bluetooth feature but too many bad reviews. Otherwise I'm really pleased with it. The lights are very helpful.
Very smart charger.
So far so good all working well. I have converted to lithium and used this charging method. Its a little early to tell but it has increased my fuel consumption considerably. This is probably due to less strain on the alternator and better use of the solar.
