    • Saves so much time - definitely worth it.
It was much cheaper than the Milwaukee brand and works so well. The only issue is it doesn't come with a battery, so you need to have Dewalt batteries. I already have 3 so didn't need one and saved money not having to buy the battery. There's no way I could do my pex plumbing without this thing. I started out with a manual expander and while it's a good workout, not feasible for doing more than 5 connectors a day - you too muscle fatigues with the manual expanders. Each extender takes like 15 seconds and you just pull the trigger. Can't believe I waited so long to buy it. ... show more

    • Powerful and fast - does what I needed
This tool has helped allow me to switch to PEX in my plumbing work at home. It was expensive, yes, but wow, what a game changer! Way better than the Milwaukee, by the way. I bought it, compared it, returned it. The DeWalt is just better. Faster and more powerful.

    • This tool works great
I installed pex A in my entire house with this tool and it works great. I am not a plumber. Every single joint was made with no leaks on the first try. This tool makes it too easy to complete plumbing yourself.

    • Meets my needs as a DIYer
This is obviously much more efficient than the manual tool for PEX expansion. I’ve used it to repair plumbing for an auxiliary building and my landscape irrigation line. It operates as expected and I haven’t had any issues so far. It comes with the 3 heads, the lube and the case, as described. It was also less expensive than competitors’. I’m happy with it! ... show more

    • The only tool for PEX-A expansion
This tool is awesome. It works great and is fast. The tool comes with expansion heads for 1/2, 3/4, and 1 inch pex fittings. This kit has no battery or charger and since there were Dewalt batteries in my shop it made sense to get the bare tool. Plumbed an entire utility room with a pex manifold only took about 2 hours and would have been an all day job in copper. The hand operated tool is good for a here and there but not as good for 50 connections on a full re-plumbing job and this power expansion tool makes this job seem way too easy. Thats a good thing. Be sure to keep the cone portion of the tool clean and lubed with the special lubricant which comes in the tube. Remove the expansion head and clean the inside of the expansion head and the cone and apply lube. If you use too much lubricant then it will seep through the expansion head and get inside the pex tubing which does not seem to be an issue. Just wipe off the expansion head of the excess and keep working. Too little lubricant would shorten the life of the expansion head. It also has a hook that you can mount on either side and the head comes with a hook already. The hook on the head seemed a bit unhandy to use and preferred to use the hook mounted at the battery end of the tool and it made for a more natural grip when reaching for the tool when hung on your tool belt. Milwaukee makes a tool and seems like the head of the tools are identical. One may directly compare the two and for my use it made more sense to maintain battery compatibility. ... show more

    • Convenient, Modern Way to Plumb
I’ve been happy with this tool although, I haven’t had cause to use the 1” expander. Mainly ³⁄₄” around my water heater. Amazingly quick and problem free compared to soldering. But, you have to do some soldering to get started with an adapter. I like that PEX-A is full flow and that the piping is cheap. I probably don’t do enough plumbing to justify the cost of this tool but it is pretty cool and I’ll gradually get some use out of it. ... show more

    • Works like a champ
100+ connections and not one leak. I do 5-6 clicks for 1/2" and 8-9 for 3/4" --- wait 45 minutes or more, turn water on, you're all set.
