Wrong product shipped
by Matthew from Ithaca, New York on September 28, 2013
When I bought this product from the web site it was listed as a single LED replacement lamp, and the photo was clearly of and LED lamp. I ordered 4 of them. What I got was 4 two packs of regular filament type lamps. This was clearly a mistake on the part of iboats shipping the wrong product. I requested the correct product multiple times and in the end it looks like I am being forced to pay return shipping for their mistake and they are not going to make good on the product that I ordered. Needles to say I am very unhappy with iboats and I will not be placing another order with them. I gave them every opportunity to make good on this transaction and they never got back to me. Regardless of the product I would urge you to consider that if this company sends you the wrong product that you will at a minimum get stuck with return shipping costs for their mistakes. I would also urge to you try contacting customer service before you place an order and see if you get a reply pre sales. It will not get any better post sale. As I said, I will never buy from them again and I gave them every chance to make good on it.
