This Tool and Pex-A is the only way to go.....

I'll never go back to pex crimp fittings after using this thing. This tool, along with pex-a tubing and expansion fittings are the bee's knees.One of the hot water copper lines in our house developed a random leak under the slab. Never have dealt with that before in any house we've owned. So, my only options were to bust the slab up and repair the line, or abandon the leaking line and run a new pex-a line off the hot water manifold up and over through the attic and down to our master bath. Naturally, I opted for the latter, along with insulating the line in the attic.I did a bunch of research on this tool and the Milwaukee M12, and ultimately decided on the DeWalt. The tool is like any of my other DeWalt tools I have, meaning it feels like a quality tool and performs great. The tool is balanced well, and it expands the pex-a tubing and expansion collar flawlessly.The tool is dang pricey, but after watching countless videos on YouTube and reading reviews on pex-a vs pex-b and crimp fittings, I opted for the DeWalt expansion tool and to replumb with pex-a. The money spent was well worth it as I have complete confidence in the install. Once again, this tool and pex-a expansion fittings are the way to go.

This Thing Rocks

I had to replace a pressure tank for our house's well water supply after the old one blew water everywhere spectacularly. I had assisted (or more accurately watched) our plumber friend install the original system using pex-a/uponor tubing and a battery powered pex expander.In my deluded mind, I judged the job of replacing approximately 4 feet of 1" pex tubing with 6 joints and reusing a metal shut off valve as easily accomplished using a manual expander tool...In case you are wondering if I had actually tried the manual spreader prior to my emergent project, I had, but with one small difference. I had connected 1/2" and 3/4" pex tubing joints in a controlled setting NOT in a wet environment and where I was forced to spread the connectors in awkward angles and positions.I quickly learned the folly of my deluded confidence after making several less than optimal connections which revealed through both slow and fast leaks, my utter lack of good judgement.My house went without water for the next 2 days while I waited for my Dewalt power pex-a spreader to arrive. Finally, after watching using the online tracker, my delivery driver take an extended lunch nearby then leisurely bounce around the neighborhood a mile or two away, the supply-chain gods smiled upon me and I had my new tool in hand.From that point, the longest part of my project was waiting for the battery pack to fully charge. I popped the second battery onto the charger just in case, but the first one did the trick solo. The design of the tool was perfectly suited to the confined and cramped space I was forced to work in. But, the best part was the raw power that this expander has, which (as I now understand) one needs when using 1" pex-a tubing to plumb a project.I looked at the reviews for both this unit and the Milwaukee M12 version, which was comparably priced but described as a bit underpowered for continuous 1" connection expansions and didn't really want to spend 2x the price for the more powerful Milwaukee M18 tool. I think I (finally) made a good decision and I'm finally in a leak-free house with good water pressure and flowing faucets once again.TLDR: While expensive, this unit is definitely worth it if you are plumbing a big project or expanding multiple 1" connection joints

This tool works great.

Great price.

Giving 5 stars for the price. Did not use tool as I had the plumbers just come and fix the problem. Case felt heavy and it has good reviews. Return was easy peasy.

Great tool, but........

Instructions were weak regarding how much grease to use and where to place it. The expander attachments need to have a liberal amount both on the outside but most importantly in between each blade. This is a MUST !! My expander blades locked up numerous times because I didn't have enough grease. Lesson learned. Once I learned this trick, this tool performed like a beast !!
