A couple of practice pieces and was amazed how well it worked. Easy to use. Practice on rotating tool and moving to the next size when you can and worked great.

Couplers are going to be a thing of the past. Save money and easy to sweat in.

Easy to use and works great just have to be careful not to over stretch the pipe but otherwise it is compact and I was impressed with the workmanship of the product not a light weight but well done. Bravo

I do refrigeration repairs professionally and use this often. Flawless operation.

Great product, will save me tons of money on fittings

Works much better than the hammer ones

Gotta be very careful not to split the copper

This tool works well and is a good value. If improvement was to be made, the length of the swage sections could be a little longer to allow for easier assembly of swaged tubing assemblies.
