Welcome aboard!
I've heard from a few people locally that some of the best quality devices are Smok and GeekVape. There are other high-quality systems for the big professional players, which I don't use. I'm a newbie, but compared to my Vaporesso Xros Pro, which I recently retired, I really love this GeekVape Digi Max. I vape it all day, and I'm lucky if it drops below 97% battery level. It’s probably twice as heavy and twice as large as the Vaporesso, but it fits just fine in my shirt pocket. Its available with both fixed coil pods and separate pods with replaceable coils. I can tell the accuracy of the wattage seems to be very accurate, imo. I also really like the large 5ml pod! Good luck and happy trails..
