Looking at this thing online brought a few questions. Since it's not a symmetrical hexagon it threw me off for its ergonomics but holy cow was I wrong. I've felt the Topside Dual, and the Pulse Dual, but neither of them can hold a candle to how this feels in the hand. With the Topside, it's too bulgy and for the Pulse Dual it's too short and getting to the batteries can be a pain. This though, feels like it's made by people who have hands. It's light enough that it's comparable to my other dual battery mods, and being able to put a 30mm on top is accommodating for the kind of power you'd get out of a dual battery.
Compared to the Topside and Pulse Dual, the price point may seem like a big issue but honestly it's worth it. If you can afford it, go for it. If not for the ergonomics, then for the fact it has one of (if not the) best chip on the market. (also I have the black and stainless steel variant and thing looks sexy af)
