A terrific transaction. Mark was great to deal with, conversation was enjoyable, and he was also kind enough to offer some insight on helping me pick out a new cell phone. I wouldn't hesitate to buy from him again. Thank you!

Really nice guy, He is very polite and helpful.. He is highly trustworthy, He offered me a 10$ refund because the shipping was a little bit cheaper. that's really noble of him! The headphones were in excellent condition just like he said. Thank you Mark!

Excellent transaction. Mark was very responsive and thoughtful when he answered my questions. The Ipod arrived carefully packed and just as he described. As a bonus he included another Ipod video that just needed a new battery. Merci!
