Recharging works thanks to the USB adapter with no problems, but the battery does not hold in my opinion long enough.
Priced the E-hookah with 15.95 is good, it is worthwhile in any case (but the price has risen)
I additionally ordered me refill cartridges Blueberry Mint, but I am not convinced. The taste comes through hard and sometimes it scratches something in my throat.
Unfortunately for this e-Shisha "only" 4 stars, because of the battery and because prices are rising (9.95 for a 5 Series Refill me personally too much!)
A little tip from me: Ordered you prefer a mix refill, since the same flavor of a time "boring" is!
