Sure, it’s not the quality of a Bosch. But hey — for $10 you can own your own heat gun. This cheapie from Harbor Freight works great for shrinking tubing or removing glued-on emblems from vehicles. (Just take your time and don’t melt the paint.)
I own a similar model also from HF, and I’ve had pretty good luck with it. Both the one pictured and the one I own are 1500W models, drawing 11-1/2A via a standard 120V outlet. This one appears to offer more insulation than mine, though the handle on mine never really gets hot. A three-way switch lets you select from two heat levels and “off.”
As always, YMMV. But how much mileage do you need to get out of this $10 unit before you get your money’s worth?
