"Nice and easy to install, good clear instructions. Would be great if the smart hub was Bluetooth compatible"
"I purchased the 40A dcdc and hub kit, i had to cut the anderson plugs off as they dont connect to the hub, The 20A dcdc charger looks like a better and easier setup to the hub. You cant get 3 x 8AWG wires into the earth socket on the hub."
"great piece of kit works very well and easy to inslall also at a great price . Thank You"
"I had a problem with the first charger but got in contact with Sunyee, and they replaced it straight away. I am very happy with the service."
"Great quantity and everything works well."
