Good question. For dabs, I’ve personally leaned toward devices that have adjustable wattage and a herb coil option, because they let you fine-tune the heat so you don’t burn your concentrate or lose flavor.
One device I’ve trusted over time is a mod that’s rugged but compact so even when I’m dialing in for thick wax, it still feels stable in my hand. It also has enough power to vaporize without combusting, which helped preserve both flavor and my sanity.
If you're open to pods, I’ve also tried
got a Just Twist 3000 it’s sleek, works well with concentrates in low-watt settings, and doesn’t feel finicky.
