Bought 10x 18650 cells from him for $25 shipped. Overnight shipped. Arrived in, I believe, <24 hours. Worked great. Will buy again. Recommended to everyone.
I also had a great experience with him. I paid $15 for 5 18650's and gave him my address. When it wouldn't work in the USPS label generator, he then gave me a call to confirm everything was as it should be. He then proceeded to overnight the batteries to me via FedEx instead - without charging me any more for shipping, which I'm sure was not cheap.
If you get the chance to deal with him, go for it!
