So far so good, doesn't kink the pipe, does leave a little rippling on 1/2 inch, but bent 7/8 with ease, my old yellow jacket set would ripple the 7/8 and it was very difficult to bend, I love the reverse attachment because you can make U shapes with it. Would recommend this product.

Well, I'll be honest by saying I did not want to pay over $300 and buy one similar at my local suppliers because I was not sure how well it would work or if if would last long.

So I purchased this one at a lower price but still had a recognizable brand name.
I have used it 10 to 12 times so far and now do not use my spring benders any longer that I have sworn by for many years.
The quality seems good and I like the color coding of the mandrels and the insert pieces.
I have not had any issues with the copper crimping on the inside edge which could be due to quality copper.

You'll also save on fittings which is nice, but mostly you'll not have the extra joints to braze which makes for a more reliable install which is nice.

The only problem I have is "I should have bought this years ago"

Well its been 9 months and I have to say I'm very impressed with this tool. My installs not only look cleaner but are definitely more reliable because the bending of pipe out of the wall or ceiling, combined with a hand pump swager kit I purchased at the same time, has minimized braze joints and virtually eliminated the need for any couplings or 90 deg elbows.
Plus this kit comes with the attachments to allow the tool to reverse the bend direction which I've used many times for clean and efficient piping into an AC or coil. Many kits don't come with the reversing parts - they have to be bought seperately.

Very Solid Unit, the Aluminum Mandrels are very nice compared to others, only thing I wish was different are the plastic clasps on the case, may fail with time, overall, great product for the price.

After buying it for a few months, it is very convenient to use.

I got this to help my brother-in-law do a mini split in his porch. (He was the doer I was the teller!) We had some pretty crazy bends to make and needed the ability to bend in reverse. We made about 8 bends in both 1/4 and 5/8ths copper. It was not real easy with the 5/8ths but it worked pretty well overall. I have no clue how it would hold up if I were to use it everyday but it seems to be well made. I also know that the mandrels being aluminum is WAY better then hard plastic. The aluminum does not kink the pipe like the plastic does. I read reviews where the ratchet went kaput. I didn't have that problem nor did it seem like it was slipping at all. If I have a chance to lend the tool out to any friends in the next 6 months I will update the review if anything was to go wrong with the tool, but overall it seems to be of very good quality. I would say give it a shot. They seem to be pretty attentive since they contacted me twice to see if I had any questions or problems, which is very nice.
