Mine was delivered earlier this afternoon so I have only spent a couple of hours with it.
The device has a nice appearance; everything lines up and looks good. It has nice rounded corners and feels good in the hand. It seems a bit lighter for its size compared to the Cana DNA30, but still feels solid. The buttons are clicky, but are definitely of a cheaper variety. There is button rattle comparable to my Sigelei 50W. The magnets for the back plate are quite strong and it requires some oomph to take off. It does not have a floating pin but it is adjustable.
I put a 26650 32/64A 3500 mah purple Efest battery in and it fired right up. The ohms reading is dead on compared to the rest of my devices and ohm readers and doesn't jump around. It seems to be operating like a champ.
Unfortunately, I only own a Cana DNA30 and Sigelei 50W so I'm afraid I can't compare its performance at higher wattages. As pure speculation, I'd hazard that Cloupor has continued with its tradition of being overly optimistic about their device's output power. For someone like me who hovers around 30W to 50W that really isn't a problem.
Thus far, all in all, I'm quite happy considering the ~$95 I paid for it.
