I use a Firewood 5 and a Firewood 7 every day. I got started with a firefly 2 that I need to send in for maintenance. Those are the only purchases I've made worth mentioning. I love them all. They've all got great temperature control. I love the way the firefly has a little app that gives a bit more precise settings, but I get right where I need to go with the firewoods too. With the Firewoods: I don't mind needing to look up how many buttons I'd need to click to set a temperature, and to be honest I haven't changed the temperatures on my presets in years. I just go between preset 1 2 or 3 depending on whether I'm inside, outside, or I'm outside and it's windy. Y'know, sometimes you want the one that connects to your phone, sometimes you want the one that doesn't. I'm thinking of saving up for the volcano next.
