I just got mine in the mail and man, these things are so nicely made. The design and machining of this device is both functional and beautiful. I do like the way the longer radiator looks on the T1, having so many fins just looks neat, but I think that overall I like the look of this one better. That was a pleasant surprise because initially I thought the T1 was better looking but that was before I actually saw the T2 in real life. Man I just really love good machining and that's for sure what you get with Mad Heaters. I love good machining so much that I spent like $100 on a case to hold my vitamins and I only did it because they're so satisfying to hold in my hands and use. The people who made these, both design and execution, really know what they're doing and it shows. I can't stop looking at and just admiring it. It's almost a work of art and I don't even want to desecrate it by loading it up and hitting it with a torch lol.
I also did notice like others that the cap slips sometimes when trying to use the magnet on the reload I ordered with my T2. It was too tight out of the box to unscrew it and my screw is counter sunk properly. The thing I've found that works is to make sure that you tighten it with the magnet as well. As long as you're not grabbing it and tightening it by hand or with a different tool, you shouldn't be able to over tighten it to the point where the magnet won't grab hard enough
