Was important to me that the battery can be adjusted and has sufficient power (20W and 2200mAh) and I must say that he really just that. I use it at the moment with the Eleaf GS Air, this I can only say good. Taste 1 and 1 + steam ... naturally herrumprobieren after a little. Next he leigt just great in the hand, is not too large and brings as already mentioned tidy performance, shall be called at moderate use as 1.5 to 2 days battery life. The store is fairly easy via a miniUSB connector. Here you can in the 20W variant its settings not sure, so when you come to the arrow keys to change the watt or voltage, in the 30W version this option is probably available.
Everything else is super. He has a shut-off after 10sec continuous fire, can be regulated in Watt and Volt range, the workmanship is good and it works quite dibasic.
All in all a recommendable ModBox for little money.
