Picked up one of these recently. It's more or less your standard AA box mod with a 510 connector, except it has a built-in charging circuit much like the original 510 3.7v USB passthrough, or similar to the Bartleby mod.
It's about what you'd expect from a 3.7v mod. It uses a 3 amp horn switch, has an on/off safety switch (built into the AA box), and a mini USB 5 pin connector. It also shipped with an UltraFire 14500 900 mah battery and retractable USB cable, no extra charge.
My main unit until now had been a MadVapes AA box, but like all units made from plastic, it'd been tossed around a bit and was a little worse for wear (and somehow the 510 connector's center post became recessed just enough that it required putting a tiny sliver of tin foil on the atomizer in order to make the connection). I purchased this as a replacement.
On the plus side, it's well constructed and doesn't have any glaring faults. The charging circuit fits neatly into the unit and doesn't add to the overall weight. The choice of being able to use USB power when I'm at my desk and then simply unplug and walk away with a full charge is another nice feature. And the sale price is around $30 right now, making it relatively affordable.
On the negative side, it's a plastic mod. It's sturdy enough for everyday use but it won't take many drops or impacts; let this hit something hard enough or perhaps accidentally sit on it, and it's in pieces. Another negative (for me) is the lack of an indicator LED. While the charger has an LED to show when the battery is full, it lacks one to indicate when the button's been pressed. This might be desirable for some, but when I was using my MadVapes AA mod, the LED indicator would be a way to tell when the battery was low . . . and I just like to be able to know when the power's flowing. YMMV. (Incidentally, I fixed this myself by cannibalizing a long-dead 901 battery and inserting its LED wafer into the circuit. Since the unit's translucent, no drilling was required.)
This is not gonna replace the high-end mods, but it's a good starter unit. It's reliable, compact, and the built-in charger makes it completely self contained. The inclusion of the battery makes this pretty much a steal. It's good for everyday use, sitting at the computer or even as a reliable backup. For the price, it's more convenient for most to buy than build. I'd happily recommend it and if this one breaks, I'd buy another to replace it.
