Great so far!
I’ve only used the straightener a couple of times so I can’t speak on the durability but it’s weight and feel make me thing it’ll last a long time. I’m amazed how well this tool straightens tubing. Once you get the tube through the tool, straightening is a breeze as all you have to do is pull it back and forth a few times. I was working with stainless steel and very happy with the results. This is a must for anyone who’s using coiled tubing for brake lines.

Great tool. Quick easy and simple.
Great tool! Working on a Trail Buggy and running all hydraulic lines requires buying coils of 3/16 tubing. Uncoil, pass through the tool, and slide it back and forth a few times for perfectly straight tubing. This little tool fit in my flaring tool bag. It is lightweight and maneuverable even under the car! Professional results.

Does the job
Good for the cost. Easy to use by hand. Fits in a bench vise if you want. Wasn’t perfect straight but by the time you add the real bends it looks proper Leave extra length because the ends don’t straighten as well as the middle section of tubing

Like magic.
Nothing like straightening out a piece of tubing that had multiple bends in it. Even tried it out on a 180 degree bend and it did an amazing job. One of the screws that hold one of the wheels in place came off so I tightened all of them. Maybe I'll go back and put some lock-tite on all the screws. Going to get me a 3/8" and a 1/2" straightener next. I like to get at least two to three uses out of the copper tubing before tossing it in the recycle bin. I go through a lot of copper tubing with my students, and this definitely paid for itself after the first use. My students had a great time straightening all their used tubing. Little tip when using it. Rotate the tubing or the straightener as you pass the tube through the tool. For the 180 degree bend, I pulled the tubing as straight as possible by hand and then used a soft face mallet to lightly tap on the remaining bend until it would go into the tool. Once in the straightener, roll it back and forth while twisting the tube or the tool and that last bit of bend flattens out just fine.

The right tool for the job
This thin works awesome. It's a little tricky to use at first because you have to find a balance between straightening the tube and pulling/pushing too hard and re-bending it. It's a very quick learning curve though, and after that you'll be making arrow straight lines in no time. Works very quickly too, you can do a 6 foot line in less than a minute. A great tool for the money.

I picked up this handheld tubing straightener to help with my custom fuel and brake line projects, and it’s been a real time-saver. Out of the box, it feels solid — heavy-duty enough for regular use without feeling cheap. The rollers are smooth and easy to adjust. I’ve mainly used it on 3/8” and 1/2” aluminum tubing, and it straightens coils with minimal effort. A few passes through the tool and the tubing looks almost factory-straight. It works well on softer metals like copper too, though I haven’t tried it on stainless yet (I imagine it would struggle a little without some lubricant). It’s handheld, so you can use it anywhere without needing a bench mount, which is super convenient for working in tight spaces or when you’re bending lines on the car. Pros: • Sturdy construction • Easy to adjust • Portable and lightweight • Great for aluminum, copper, and softer materials Cons: • Might be tough on harder tubing like stainless steel • No case included for storage • Takes a little practice to get perfect results Bottom line: If you’re doing any type of tubing work and need straight, professional-looking results without the crazy price tag, this is a great tool to have. Just be patient on the first few tries, and it will save you a ton of headaches later
