Works well for me

I had a high-end body shop for 20 years. Along the way you discover a lot of great tools for cutting sheet metal, angle iron, or thick plated steel. The advantage of this air cut-off tool is its speed. It can get into tight quarters and do only what a reciprocating saw can dream of. It has a blade guard to the rear. I used one once that someone said, "Here try this" and he had removed the blade guard. Well, unfortunately it kicked back putting a slice in my finger that require professional medical attention. All the years I used one of these I never even came close to an injury.
I was glad to get this one because I wanted to have one in my basement shop, as well as in the garage tool box for ease of use, and accessibility. The price of this thing is insane and makes it practical to have more than one. I like the safety catch on the pull-on paddle so you can be sure that you intend for it to start up rather than, just for example laying it on a table, and it takes off. Stock up on cutting discs. This comes with one mounted on the tool, as well as the wrench, and an air fitting which may, or may not be the style you already have.
I can't tell you how many times I am in the garage, or in the basement workshop and spent lots of time looking for my cut-off tool, only to discover that it is in the other shop. Having an extra conveniently on location is worth the price of admission alone.

This design is like 30-years old. It's reliable. It works great. It's the same tool that has sold under dozens of brand names.

But, surely there is a better solution than the hingey, pinchy on/off lever safety. The design is awkward if you haven't noticed. The "roll yer thumb to release the safety" is just clunky.

I like this cut off tool. It's pretty powerful, and doesn't take much air to run. I have a 60 gal compressor, so I'm not worried about that part, but that's good for people with smaller compressors.

This seems to have the power to chew through just about anything you throw at it. I tested it with the wheel they sent and it worked great.

I like the safety on the handle, this isn't going to just go crazy on you when you set it down. You have to purposely depress the level to get it to run. I'm happy with this, I'll be using it for body work on one of my trucks. I can't see any reason not to recommend it. For the price, this is a great tool.

When in tight spaces these are a must, this thing has adequate power for the tasks iv used it on. The overall construction is nice and seems durable. The etchings are a bit sharp but for the price it comes in at that's a small con. The trigger action is nice and smooth and it's easy to control as well which is a plus. Overall I definitely recommend this cut off tool.
