fixing is correct and fairly easy, the big problems only come from ridiculously short power cable (about 20 / 30cm can be provided without taking .. of course .. So once stripped cable (which are very very thin and fragile, I still intersected the coast after pinched cables in the new decision because those Ci is severed just crushing!) it really remains a destitute cable end .. the waterproof plug will cost you a few euros of course
In the end it was a cheap product that really good job but clearly we just pay for, no more, no less
