My title says it all, i have only positive experience with LeLightGo
I've ordered 2 sets, for razor crest and batwing. From 1 set a Led was missing, but they replied quickly on my request and send it after. I've also requested an upgrade of 1 set, that was no problem at all, a balance price was separately registered and payed. The instructions are quite straight forward, for me it was not difficult.
