This thing is amazing on some of the youtube videos I've seen. https://smile.amazon.com/Profession...8&hvtargid=pla-1008201266832&sa-no-redirect=1
Never seen that tool that low in price...with that said, it does work pretty awesome as the heat stays concentrated, unlike when using a hot wrench (torch). Heat fastener, allow to cool, try to remove...if it doesn't loosen first time, lather, rinse, repeat.
They work good... especially on rusty gas tank bolts.
They get the job done
I tried one, works good if you have to use it. If you are working in an open area, torch is the way to go. I know some of the mines love it because every time they light a torch they have to fill out paperwork. This has no open flame so no extra safety BS.
I bet it would work good on corroded battery hold downs, i might have to get me one i have never seen one priced so low either
It is crazy how quick it cherrys a bolt!
I've never seen a tool like that, that's why I posted it, to spread the word.
