I also got one recently. I really like it. The temperature control does seem more accurate than the DNA40 and the SX-330 V4S, especially on lower ohm builds. I feel as though the vapor production is more consistent with the device. I also currently own a VaporShark RDNA40 (Big Screen, no resistance lock), and an IPV4 (Black).
When I turn on the device, it does say Liasimo.
Size-wise, it's narrower than a Sigelei 150w, but much thicker. About the same thickness as the IPV4 with it's battery case on. It's also heavier than both devices, because of the tempered glass and stainless steel design.
I haven't done a tear-down yet, but am considering it. If I do, I will post pictures.
Currently I'm running my Zephyrus on it with a dual coil NI200 build, 28 gauge, 2.5mm, with 11 wraps.
