So I have been using my Wismec Presa for a week, here are my thoughts so far.
The fire bar really is awesome! It separates this mod from all the others. Another thing I really is the USB charging port is on the back of the mod & not the bottom, it makes charging much easier than mods with the USB port on the bottom. The build quality is excellent, I especially like the quality of the 510 thread. I also really like the physical lock button, it quickly disables the device without having to click 5 times. I use the lock button often. Accidental firing has not been a problem.
Batter life is OK, not great. Despite it having 400mah more battery capacity than my 30 watt Istick its battery life is not any better & it might actually be a little worse
I could easily get two full days out of my 30 watt Istick, sometimes I have to charge my Presa before the end of day 2.
I suspect this mod could be firing a little low. I always set my Istick at 15 watts, but I have to set my Presa to 16 or 17 to get the same vape. If its not firing low this could explain the battery life. I don't have a volt meter to check this.
Now for what I don't like. Those two sharp corners below the fire bar became a MAJOR pain in the ass or hand actually. Both of my hands where sore after using it for two days because they where constantly getting poked by the sharp corners! I ended up grinding off the sharp corners with a dremel and then polished them to a smooth finish. The sharp corners really bothered me. If you don't have the ability to shave off the sharp corners I would NOT buy this mod. Now that I have removed the sharp corners this mod feels excellent in my hand.
After using it for a week I would say this Mod is OK. Overall I am satisfied with it, but not overly thrilled. The fire bar and comfort of it (now that I have removed the sharp corners) are the best things about this mod.
