Brilliant piece of kit
Fitted it to my van. Has been working great. Instructions are very clear. finding a hole or making a hole to run the cable to the car battery was a bit tricky but it depends on the model. Some models have easily Accessible pre drilled holes. My kangoo was a bit of a nightmare. I had to remove my car battery and air filter to gain enough access to drill a hole. Once this was done it was very easy. Ran cable into cab under the passenger door seal and into the back where my deep cycle battery is located. so much easier than taking it out every couple of weeks to recharge. once fitted just drive around and the battery is charged. Very happy.

Don't skimp on length
All components were great and worked well- the only thing that i felt was misleading was the length of cable runs- the longest was 2.2 + 2 x 400mm short ones- had to re configure. Would have gone for the 5m one if i'd known
