From the "Smok xPro M50 Mini Box Mod" thread...comparing it to the iStick:
ObsceneJesster: Fit and finish is great. It feels solid, the power button is tactile and the buttons click when pressed. The size of the device is perfect in my opinion. It's not to small and not to large. It fits perfectly in the palm of an average sized hand. The amount of power packed into this little device is insane.
All in all, I am very impressed with this mod. When I leave the house, I will be grabbing this over my iStick. Not just because it's more powerful but it also feels better in the hand.
skjames19: Size: Its hard to get an idea of the actual size by looking at pictures online. Even watching videos on youtube seems doesnt give you an actual sense of its size. If you have an istick, the m50 feels and looks like a bloated istick. its BARELY maybe 10% larger, BUT that is the difference between looking just a tad to big to being the perfect size. My coworker even mentioned that my istick seemed small, but this m50 looks like a tank. That extra 10mm in height from 75mm to 85mm is huge when it comes to perceived size, even though its such a small difference. Same goes with the width, its barely wider than an istick, but added with the bit of height, other people seem to think this is too big but the istick seemed small.
I had planned for this to be my out and about mod, but like i mentioned, its just baaarely too big for my liking. Not only the slight larger increase in size, but design also has a lot to do with perceived size. The more boxy a mod is, the bigger it looks. The istick had curves to make you think it was smaller than it actually was.
Rating: If I rate the istick at 8, -2 for the crappy pin, id rate this a 7, -2 for the no pass through and -1 for its slightly larger actual and perceived(boxy=this vs curves=isitck) size.
