Pros:It worksIt is not too priceyIt uses standard bitsIt uses your existing air hammer to break loose rust.Cons:Not an 'impact driver', you use your hand to provide the 'twist',Requires a fair amount of space to use.Summary: It works pretty well for breaking loose rusted screws and fasteners, using your existing air hammer as a power source. The way it works, is you push on the hammer, to engage the screw, press the trigger on your hammer to seat the bit, and then use the handle to loosen the screw/bolt. The hammering of your air hammer does not impart any twist to the fastener, you must do that manually with the handle, which is actually a good thing. If the screw heads are buggered up, you don't have to impart any 'twist' that can bugger them up worse, until the hammering causes the bit to bottom out in the socket. The hammering causes the bit to engage solidly, and the vibrations break loose rust, allowing you to carefully apply force to loosen the screw. If you watch closely (wearing goggles for safety) you can very slowly turn the bit, completely under your control, so it does not slip. I found it works better than an impact driver, for breaking loose rusted screws, because if the bit isn't engaged tightly enough to the screw, even an impact driver will slip, and bugger it up. With this tool, you can actually 'hammer' the bit tightly into the head, before you try to turn it. Keep in mind, the tool is not terribly compact, and when you add the length of your hammer, it requires even more space. Also, it is not practical to use to completely remove fasteners, as it is awkward to turn the handle much more than halfway around at one time (which also takes quite a bit of space to do).However, for the job I think it was intended, which would be breaking loose seemingly rusted solid screws, it does very well, provided you have enough room to work. Once 'broken loose' you are better off putting this tool aside, and using a standard screwdriver, or impact driver to finish removing the fastener. I think where this tool would shine, would be in something like auto restoration, where you want to remove rusted fasteners, and not risk damaging the surrounding finish, like you could, if you just drilled the old screws out.Thexton has a reputation for making and providing high quality USA tools and test equipment. Ibwas surprised to find China production bits in this set, making me question if any of this set is actually built in the USA.The provided bits are soft and of poor quality. I will update this review if the mechanism of the tool has any issues.A better alternative would be the Mayhew Shake and Break set with an additional bit adaptor. The Mayhew set is also available on Amazon and proudly made in the USA.It is rare you buy a tool that really works as good as you had hoped it would. I can't think of a single tool I own that exceeds my expectations like this one. It is crazy how easy I can now remove the screws form Honda and Toyota rotors. I used to struggle a little with rotor screws, you know the drill....use two hammers to loosen.... then a manual impact screwdriver.... a few choice words and if I was lucky I would be success in removing the rotor screws withing 5 or 10 minutes. If not I'd drill the heads off remove the threads. Not hard but annoying and time consuming. I rarely use an air hammer and only have a very inexpensive one (think it still only cost $10). I do have a good compressor though. I didn't really think my cheap air hammer had enough power to use this tool. I was wrong. The very first screw I tried was already very stripped and I was about to drill off the head to remove. I figured since I needed to drill the head off anyway, why not give this tool a try. The screw came out in less than 5 seconds. It was crazy. Now I do live in Georgia so I don't have the rust issues like up north, but rotor screws are still a pain no matter where you live. The most amazing thing is I have now used it on other screws that were very rusty and stripped. It has taken every one of them off even when there was almost nothing to grab onto. I find myself looking for rusted half stripped screws so I can use this tool.Gets those rusted screws on brake drums out without breaking them. Made in USA great productI have to say at first glance, this is a great idea for removing those stuck fasteners. Out-of-the-box the set up is very simple. There is a problem once you use the tool though. The interchangeable bit becomes lodged in the end of the tool. I don’t care what you do, it is impossible to remove once it has been hammered on with the pneumatic tool. When, not if, you break the Phillips head bit that is included, you are out of luck trying to replace the bit. I have tried everything from mechanical force, to heat, to remove the bit. No dice. So in my opinion it’s a one time use tool. I did find a great alternative though. (See the picture). This set up allows you to use sockets and whatever you want to use in the socket. Same idea, better execution. Much tougher. It’s called a shake ‘n’ break 3/8” driver. I’ve had much better luck with this set up. Once again it allows you to use sockets or bits. hope this helps.If you do not own one of these, i would highly suggest that you do! I used this tool along with a long barrel vibration damped air hammer to remove a set of very rusty brake rotor retaining screws from a 2005 Ford Five hundred. I live in the salt belt. This tool made VERY short work out of removing those pesky screws. This is a great product. There is another variant of this tool that you would use with impact sockets that works really good too!
