Just received mine today. Here are some initial thoughts
Pros: 1) Construction and design. It looks and feels great. Has a nice weight to it and the buttons do not rattle. 2) Usb port seems sturdy. 3) It seems to work as it should.
Cons: 1) Cant vape while charging! 2) Need to unscrew to get battery out. 3) ohm meter is a bit jumpy. To check the ohm, you have to press the fire button, it doesnt show the ohm when you screw it on. When I made the coil, it read 1.2ohm, then through out the day it would go to 1.6ohm to 1.5ohm to 1.3 to 1.4. Its at 1.3 now. Just now I checked it, it was at 1.3....sat it down and picked it up again and pressed fire, it was 1.4ohms. * I think this may have to do with the juices on the coil, because everytime I vape it, it usually settles at 1.2-1.3 but then when gravity brings the juices on the coil, the resistance seems to jump up a bit. I know this because when I 1st fill my atty, it always has a high resistance till I vape the juices off my coil. So I guess this might not be a problem with the m50, but just letting you guys know.
Other thoughts:
Spring loaded pin: After the crappy pin on my istick, I wanted to really check this aspect of the m50 out. I pushed down on it with a flat tip and it doesnt seem to go down that much at all. Maybe 1-2mm at most. Screwed on my GP spheroid and there is a small gap. Im too scared to try to screw it down all the way to see if I can close that gap, but its on there pretty firm right now.
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.
Final thoughts: Its not what I had hoped it would be, especially the pass through was a downer. Do I feel ripped off? No, for about 50 bucks....this thing is def not a rip off. 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. Ill be using this for the time being. It not bad.
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. Sorry if I sound like an istick fanboy but its the only other VW mod I have ever owned.
