There's still a level of satisfaction when it comes to getting that build EXACTLY right on your mech without being able to adjust the wattage. Maybe I'm just old-fashioned. But even mechs are moving over to box-style and using multiple batteries. In fact, the mech I'm using now uses four 18650 batteries in parallel. So when I use PVTSO 35A 2800mAh batteries in parallel, I have a mechanical box that's 11,200mAh with a 140A continuous discharge rate. Because of the nature of my job, I still use a lot of regulated devices, but that mech is what I consider to be my "Main" rig. But when it comes to electronics, that's just how I am. Even my phone has an aftermarket battery that's actually three LiPos for a total of 10,000mAh; over 3x the capacity that the default battery has. And,I even use mechanical keyboards at work and at home. Now that I really consider it, it's almost like the more information there is, and the more options there are to change, the more I get distracted from actually vaping. With a mech, I just build and vape. So it's probably the simplicity and reliability that pushes me more towards mechanical things.
