I would leave 0 stars if possible I went last night and bought a disposable The man had me try it before we left and it did not work He also tried to use the vape and still it did not work. He proceeded to give me a new one and started to package the one we had both put our mouth on he even asked for the mouth piece back As I was getting in my car I restock the Disposables with that same pen he and I had both already used. With No disinfectant(would still be disgusting) DO NOT SHOP HERE!! Absolutely no regards for COVID If you want strangers saliva spend your money here!! Absolutely deceitful!!
