I bought a pair of Sanyo NCR 18650GA button tops from Gearbest and they seem to be genuine because they look and perform as they should. However, I never did get my Xtar charger so what seemed like a good deal really wouldn’t have been until I contacted my credit card company before 60 days ignoring Gearbest’s suggestion that I wait longer. For some reason they reimbursed me the full amount so the cells ended up being free.
