Excellent! Just what I was looking for. Easy to use and works like a charm. Only (slight) disappointment was that the charger does not include a cube, but for this price point that's OK.
G Pen Pro I bought was exactly as pictured and am very happy with it. Service was fantastic, checkout was easy and shipped SUPER FAST! Very pleased overall. Will definitely be purchasing more things from here.
Good quality product for the price. Easy to use and sufficient size chamber for the occasional user. When removing the chamber cap, the silicone mouth peace usually comes off of the cap. Not a big deal but requires a bit of adjustment when putting everything back together. Good entry level product and satisfied by the performance of it.
