I've fitted 3 of these kits now from this eBay supplier.
Excellent quality, the dual controller is very good as it keeps starting battery topped up too and coupled to the remote monitor it is superb. The price is really really good, for the specs/output/quality and the service from Photonic-universe is second to none.
I've no connection to the company other than very pleased customer with their products and service.
