Review on Mlife Mini Heat Gun - 300 Watt - Dual-Temperature Heat Tool with 6.5FT Power 🔥 Cord for Acrylic Resin Cups, Tumblers, Embossing, Shrink Wrapping, Paint Drying, Crafting, Electronics DIY - Pink by Jessica Lewis

At the lowest setting the resin will move if you hold it in one spot for too long, but it will take care of the air bubbles and remove/lift them to the surface. I've never had to use higher settings as lower settings work just fine. I only use it at 3 minute intervals, and with a maximum run time of 15 minutes, that's enough to get the job done. I have no way of seeing what temp it's blowing at but it gets warm and the nozzle can be hot so be careful but the area you're holding doesn't get hot or anything and it's comfortable to hold. . And of course, watch out for the cord, it's easy to accidentally hang it on something or knock something over with it. In general, I am satisfied with the product. No complaints, does what it's supposed to, came well packaged and with the right instructions and warning. I don't use it enough to say if it's worth upgrading to a more expensive one for anything more than hobby use, but if you need a heat gun from time to time then this is for you!
