This induction heater is outstanding!! A must have if you live in the rust belt. For me, living on long Island NY where everything is rusted and seized, buying this was a no brainer. Nice thick power cord, blow molded case isn't overly big for no reason like most tools you buy these days.
Comes with a few coils to get you started, but I recommend you buy an extra pack of various sizes. Induction Innovations has a wide range of coil sizes and styles.
Definitely a little pricey but I see this being perfect for areas you really don't want an open flame, like fuel tank straps. Also great for frozen brake bleeders. Being able to quickly add flameless heat to an specific area without worrying about damage to surrounding areas. Also just found out they make thin low profile coils to fit around lug nuts inside the rim. Definitely be buying those. Can't tell you how many Jeep/Dodge lug nuts I've had to melt out with a torch, effectively ruining the rim.
