Induction Innovations - Mini-Ductor Venom HP (MDV-787) - Handheld Induction Heater with 3 Basic Coils, Rugged Carrier Case & Operations Manual to Safely Remove Nuts, Bolts, Bearings, & More

Great product

I bought the cheap knock-off version and it came broken. Amazon replaced it and the replacement came broken (both had parts rattling inside).I spent the extra money on this and it came working and it works pretty good.If it dies in the near future, I'll come back and report it but, right now, this gets 5 stars from me.

Used it to take off stuck nuts on exhaust manifolds for a 1967 Power Wagon. I would deduct 1/2 star if possible. My only negative comment would be that it wants go into protect (overheat) mode too quickly if you cant get the entire bolt/nut head in the coil. Worked REALLY well on the exhaust flange nut that always twists off the manifold stud. HIGHLY recommended for that kind of exhaust work and for smaller nuts. Doesn't have nearly enough power to take larger things off of shafts and bar. Works well for some things, doesn't replace the torch for others. I bought the kit with all of the other induction tips. You are going to want that as you will burn through the one that it comes with pretty quickly if using it for more than a single bolt.

One of the best tools I have. Great for exhaust manifold studs/bolts!

Works great for contact heat, like a seized nut, but if you're trying to heat a bolt seized to the metal sleeve in a bushing, the heat doesn't transfer the length of a bolt, just the area the attachment surround. Good tool though.

Wow this thing is amazing! I didn’t believe that it would work, but it really did. I was able to do a job on a 22 year old car (imagine the rust) without breaking a bolt or nut. No more having to spray PB blaster and having to wait a while for it to work. This thing is 1000% worth it if you deal with rusty stuff!!!

This was purchased, knowing it was from a third party seller and it was open box return., so before purchase I specifically asked all the important questions. However, item arrived and did not work straight out of the box did not even power up.Luckily induction innovations and the fantastic customer service. Took it in under warranty

If you're taking apart a 20 year old Duramax diesel This is the ticket! Was able to take off the exhaust manifold bolts and associated bolts for the plumbing to the turbocharger without any great effort. Sure beats the heck out of Having to use a torch! I have been working as a mechanic, aircraft, diesel trucks, regular trucks An automobiles and I sure wish I had Had one of these! Simple to use, straightforward, just look at the videos and pay attention to the instructions and you just might want to keep it underneath your pillow at night:)
