To be clear, if you want a full featured hair dryer, NO cordless hair dryer will make you happy. This tool is great if you know what to expect. I use heat guns to tint windows all day. It won't work like my Wagner, but it does a great job with the DETAILS of the film. I also use it for heat shrink tubing on remote controllers. There will NEVER be a fully functional cordless heat gun. The downside is that it eats batteries, but they all do. I have big batteries so it's not a big deal. I want the car to be as cool as other brands, maybe in the next model.
