RE: beware grayson hobby
I would strongly suggest not purchasing from Grayson Hobby. I purchased 3 LiPO batteries from them recently, two of them had a dead cell. They would not respond to my trouble ticket untill I posted the complaint on their FaceBook page. They requested I return them which I did, they then notified me that the case was closed...no new batteries or refund. Their website will not allow me to create a new trouble ticket (the only way to communicate with them) and they have blocked me from their Facebook page.
This is the second problem I have had with them, I assumed the first was a fluke.
Their biggest issue is communication, your only link to them after an order is placed is via trouble ticket. They have a phone number listed but will not respond to internet customers. There are lots of other places to buy products and I would suggest anyone over Grayson.
