Alright, so positive reviews for the iPV3 150 watt box mod for me. Sorry this will be a little hard to read as I'm just jotting down my thoughts.
Had a few issues. Hex screw came stripped from the factory from me, couldn't get it out after struggling and pulling apart all my toolboxes. The tool they give you is useless and doesn't work to get them out so expect to use your own allen wrench. The guy at the vape shop spent 20 minutes fidgiting with it and was able to get it out after telling me about 50x he wasn't sure if he'd be able to. Once I got the hex screws out and replaced them (other set of screws are included) its a lot easier.
It was a very frustrating start, but all my attys sit flush on it. It can take very low and very high builds and go from 7-150 watts. My atty sometimes leaks a bit of juice but so far after a few days of chain vaping I haven't had any juice manage to actually get inside of it. Aesthetically I think it looks nice and it feels nice in your hand after getting used to it. The lcd is nice and bright and the buttons are clicky and nice feeling, although since they're little nubs can start to bother your thumb after a bit. I find myself clicking with the side of my thumb, etc. Personally I'd prefer a big button but not too bothered by it. Doesn't come with a charging cord and its unclear which one is safe to use, so expect to unscrew it every time to replace batteries. I'm going to add magnets to work around this when I get bored of doing it. The interface is nice and easy to get to the wattage you want, although the battery indicator is always a bit off. It always says I have 1/4 battery left and I won't be able to vape at any decent wattage so I replace them. Battery life is decent for what I do. I vape between 55-70w depending on the juice and it lasts me 2-3 hours of sitting at my desk taking hits every little while. Because of this I always keep a set of spare batteries handy. Also the mod itself never gets hot, which is a plus after using a mech mod that'd get hot on me.
Overall a good experience, I'm starting to see a lot of people using them at the vape shop as well. The staff were saying a lot of people have been really liking them. I can't see myself needing to upgrade for quite a while, so for now I'll be expanding my mech collection to something a bit nicer than a clone.
