Low prices, Accurate description, great quality & durable, very fast shipping and came earlier than expected! Even the box it was shipped in is in great condition! I am so surprised with how fast I received this! Like I still have a few previous orders that I have purchased from other sellers well over a week ago and still don’t even have tracking information on those yet. But this seller EXCEEDED my expectations because not even a full 48hr later, I have my item! Highly &DEFINITELY RECOMMEND!

Received the wrong product due to the fact the seller described the wrong product. when asked to get the correct product that was described in the listing, they kept saying because of the price it was the correct product I received. They wrongfully advertised a different product and would not exchange when I called them out. Horrible customer service and still have the wrong product. Do NOT recommend buying from this seller.

The item was great! The package was very late and got lost in tracking. This had nothing to do with the seller. Dealing with FedEx was a nightmare. I think I’ll just stick with Amazon Prime from here on out just because of the terrible service by FedEx. Again, this is not the seller’s fault, but the package was supposed to be delivered more than a week ago and FedEx couldn’t give me any specific information as to how my package got lost.
