Works great used it recently

Do you know that sinking feeling you get when a screw or bolt snaps? Or maybe the head strips or rounds off? Ok.. Well, this happens to me a lot, and this kit reverses that feeling. Bloody amazing. This basically turns a LONG job into a shorter/medium and more manageable job - Which I am sure we all can appreciate.So I bought this kit to help with those problems. I've had the chance to use this several times now and it's worked every single time. So it's earned a good review in my book.A few things to keep in mind though, some screws are just F'ed.. No amount of anything will save them. You have to know when a kit like this will save you or if you have to bring in the big guns (welding). Basically, don't try to use this on something where metal has fused permanently, or applications that require a massive amount of torque, Because you're setting yourself up for failure.Today, I found myself in a pickle. Very small screw head stripped (amongst several others). Then I remembered about this kit. I was thinking, maybe it's too small, but turns out there was an extractor for this very screw size (5mm I believe). I soaked the screw in penetrate fluid, relaxed for a few, then applied subtle but stern force with the extractor; and voila!! I was able to back the screw out with almost no effort. I can tell you right now, when any DIY'er or Mechanic is able to do this, a party is almost always in favor!! So, if the makers of this kit are reading, I am having a few beers for y'all tonight!!

It's works for what I needed it to do

Worked for getting stud from sons racing go-cart haven’t used it since but seems to work great bc he did it not me! He’s 17

Rusted, stuck 10mm turbo bolt on my F350 diesel. Difficult to get at due to location, access required swivel joint at a fairly severe angle. Penetrant oil, torch etc. broke a 6 point socket, tried another 6 point socket but bolt head was slightly rounded by then and the socket couldn't grip the bolt enough to extract it. 10mm from this set broke the bolt free within 10 seconds. I used it along with a 16mm offset claw socket on the outer hex portion of the extraction socket, still needed a flex joint but at less of an angle. My next plan had been to try to cut the head of the bolt off with a die grinder/cut off wheel (which I would have had to purchase).No damage to the extractor socket.I hope to never have to use this set again but even if I don't it still will have been worth it to me for this one agonizing task.

I’ve used this tool several times on my cars and motorcycles. So far it works excellent on extracting nuts, bolts and rounded screw heads with the sockets.It is however useless so far for anything you need to drill out using the provided bits. I’ve broken several of the bits attempting to extract broken screws. Attempts at contacting any form of customers service have received zero replies.So don’t expect to get any warranty support.At least the sockets work good.3 stars cause the sockets work great and the case is quality and durable.

Excellent

Use them almost daily, ease of removal fit value and quality
