I bought a mini3, and he couldn't have done things better. Not only did he communicate and ship out quickly, he gave me a detailed list of where to find replacement parts, told me how to open it properly, and warned me away from bad stuff for it.
Sold a set of IEMs to ucrags84. He was very pleasant to communicate with and quick to respond to PMs. Payment was made instantly and off they went. Very happy with the transaction - definitely wouldn't mind dealing with him again.
