We are the only ones who offer these pre-installed. Another vendors around the internet may state the same, but we will not do any warranty work if purchased through other vendors should something go wrong, as there have been copycats of our products, so there's no way for us to be certain that it is in fact, a true exLED product. They have also modified our pictures and make it look like their own product by removing our name from all of our pictures and product titles that they have uploaded.
I know that sounds harsh, but please understand that we don't want our customers to receive an inferior product.
If you had bought directly from us (modules only, as that's what is available from Best Choice), OTD price to where you are would have costed you a LITTLE less, plus a discount for being a member here. We will also do warranty work if something goes wrong when purchased direct.
