Review: Excellent Quality - I bought this for a 2017 Sprinter we are converting. We have bought lots of bits, as you can imagine, as we are converting the van ourselves. I was really surprised by the overall quality of both the instructions and the components. It is are that for such a well-priced item you get spares of everything. We were provided with spare lugs, in case we needed to cut the cables to length, spare heat shrink, spare fuses, it was really refreshing to see. It also works very well too!
Review: So simple - This arrived via Royal Mail this morning. I am by no means a competent DIYer in fact the opposite. The instructions are so clear and precise I had this wired up in no time. Switched my van on and after about 10seconds the light came on and the voltage jumped on my leisure battery. If I can install this anyone can.
