I purchased this foam cutter to cut through the big insulation foam boards that you can get at your local hardware store. The foam boards are 24"x48"x1.5". My intention was to carve the foam into detailed letters and drawings for decorations and whatnot. Because the cutter is a probe design and not a bow cutter, I was EASILY able to make holes and maneuver to make small perforations! The amount of heat generated by this cutter is good enough to melt through foam like a hot knife through FROZEN butter. I say this because as you perform long continuous cuts, the resistance increases because the foam is passively cooling the blade. But to solve this, one must use a lot of patience and a little leverage. I found it easier to place the cutter perpendicular on a scrap piece of cardboard and just push the foam through the knife like a stationary foam cutter.I have to say, I was looking for a foam cutter for 2-3 weeks straight . I'm definitely happy with this one. Price + probe design + constant power source, I'd have to say it's good for any amateur hobbyist or even semi professional etsy'er.The only drawback is the cable is a bit short, meaning you have to set your desk or work station right next to an outlet. But fortunately, the adapter doesn't have a grounding pin so you can use one of those cheap 2 hole extension cables to increase the reach.
