An Excellent Experience (24 June 2019)

I purchased four Joyetech battery adapters for my mods. It is hard to believe that I had to order them from a company in the UK because I couldn't find them in the US. I received them in 10 days and they work perfectly. The service was outstanding and the price was very fair. Thank you!
