Two weeks going on 3 dropped it twice bent the battery cap end and straightened it out works perfect no issues doesn't get hot but I haven't pushed it to 30 watts for very long. Typical build for me is around half that. I really like this. It's big it's heavy hard to miss but with the big fogger and 26650 it vapes all day plus no problem. It has an easy one button tilt left right menu system. Button feels good not too loud but has tactile feedback. Feels good if you have big hands and strong arms. The engraving and flat surfaces around the chip on the pioneer4you and cuts on the battery tube make it look good IMO but some won't like it. Never had a misfire. Being the SX300 chip it shows the power in watts, atty resistance and voltage, a battery indicator and the battery voltage which also shows the battery droop when you fire. It doesn't have the ramp feature like the EVIC supreme, not upgradeable no USB port no custom screen just very solid always there all day vape performance. And so far perfect reliability. It hasn't done anything to suggest it won't continue to be. Unlike the EVIC Supreme which I have pressed the fire button heard the click but no vape. Which other than that the EVIC Supreme has been fine too. The only down side to this seven 30 is the size, smaller lighter units are handier in different situations.
If you don't mind DIY box modding, take a look at the SX350. It's a great modders chip. And with a 26650 it still fits in my shirt pocket. And it has a USB port for SW upgrading and charging so you don't have to take the battery out and throw on a nitecore. And the SX350 is made for SW upgrading, now up to 50W. Chips selling now come at 35W. Use whatever enclosure and decorations tickle your fancy. You can find custom box lids molded for the screen. I have yet to see a tube version, but possible if you have metal milling and lathe to cut end caps holes and threads. The SX350 chip is longer than the SX300 so I was thinking of replacing the 300 in the pioneer but when I found that out I just built a box mod with it and I'm really enjoying that too.
