Overall seems well built, easy to use,and looks cool. A slight learning curve for me to hold right just because its different than any battery I've ever used,but it sits upright,nice,easy,and solid, little to no tipping will keep your carts happy. Plenty of power,I'm getting great rips on low using a live nectar cartridge, haven't wanted to go up in temp yet.
One issue,and I feel this is the cartridge makers issue,as much as the battery manufacturers at this point in the tech. If you get a cart with a slanted tip or any kind of bidirectional mouthpiece it is often necessary to hold the battery awkwardly while you're getting a puff. Industry standard 360° or free spinning mouthpieces would help everyone.
Next issue is the charging cable. Unless I'm missing a cool feature thats not in the included reading,its ridiculously short,and will give the battery nowhere to sit when charging, its just gonna flop around, unsafe,and sloppy. The good news is most of us will have about a hundred other mini USB charging cables lying around anyway. Thats what I did.
Overall super cool,well built, unique, easy to carry battery. Great job guys!:+1:
