Gonna be re-plumbing a fairly simple farmhouse...one bath, kitchen, laundry, and down the road perhaps add a bath. I am planning Pex-A for this, and I am looking at expanders. Milwaukee and Dewalt seem safe bets, but I am curious if anyone is using the Vevor and liking it. I'm not a plumber, and this isn't a huge job. At the same time, I am not a fan of using garbage tools. So...just **** it up and go with the mainstream or give Vevor a shot?
Pex Expander?

I bought a new Milwaukee expander since it seems like most plumbers are using it. I paid $225 on Facebook Marketplace, and the seller showed me the receipt from HD where he purchased it last year, so I know it wasn't stolen. The best part of buying a name brand is that when you need parts or service, there is a company to fix it.

I wonder how many times he's used that receipt?

The first generation of expanders (and many of the cheap ones) don't rotate the die with each expansion cycle. That is known to stress PEX and lead to failures (even on PEX A, but certainly on expansion certified PEX B). That's fine, but you just need to know to manually rotate the die so the seams land on a different part of the tube with each expansion cycle.
The current crop of name brands all do that on their own. Watch some of the videos, and you'll notice the die turn a little bit each time it expands.
I have the expander, but have found that PEX A stuff isn't all that common without mail ordering or going to the $$ plumbing supply places. Home Depot has a little bit, but just enough to not have have to need, but you go there hoping they will.
Also the Pex A stuff is more $$ in general. The couple plumbers I know don't normally use it unless it's spec'd on the job, like on a commercial project, or there's a specific reason, like PEX B won't flow enough in a size, but PEX A will, and space is limited.

Neighbor built his own house, bought a used Milwaukee and sold it when he was done for what he paid for it. Free tools!
I really like PEX, expanding PEX-A, absolutely..

My 2 comments about PEX after re-plumbing one house.
Always use the largest diameter PEX that will work.
Use as few elbows and splices as possible. For corners, use those external corner braces.

I have the Milwaukee unit bought to replumb our house. Kept it and have used it several times helping friends or family.
Bought most of my supplies for the project from supplyhouse.com. But our local Menards now has some fitting and PEX A pipe, while our Lowe’s has some fittings but no pipe.

I bought the Vevor tool for a small PEX A job....I have nothing bad to say about it. It works well and does what it's supposed to do. Seems fairly well built.
Is the Vevor a manual machine? Or a cordless power tool?
Like @Junkman I bought my Milwaukee for under $300 on eBay with 2 batteries (not that that's a big deal. They are M12).
PEX systems generally have WAY fewer joints than copper, but even with all home runs, it's kinda alotta lines. Lets add them up:
I think the thing that send pros to the cordless tools like the Milwaukee is the fact that you don't do these in your lap or on a work bench. You do them immediately adjacent to the already installed pex fitting and you may have little space, or slack, and not much time to get it seated. Personally, I'd recommend the DeWalt or Milwaukee or something like that. Treat it nice and sell it when you are done for what you paid for it. The money these things cost is NOTHING compared to hiring a plumber. Now if we were talking Milwaukee pro press force logic.....different answer.
For PEX-A I buy either legit Wirsbo/uponor or Sioux Chief. And I buy from either PEXuniverse.com or supplyhouse.com, but you can shop around. I don't see PEX-A in my local home centers and wouldn't trust it. Like all plastics, PEX is sensitive to UV.
Couple tips from me:

Couple tips from me:
- PEX is a plastic like any other and is greatly effected by temperature. Running PEX lines in the winter *****. DAMHIKT When it's cold, PEX is stiff and extra unwieldy.
- PEX is pretty easy to kink. But you can repair kinks by heating it up with a heat gun until it goes clear then letting it cool. You can also gently heat it to get it into the shapes you need
- You can use PVC long elbows as corner supports in a pinch. These are usually more expensive than the black plastic ones from supplyhouse.
- Uncoilers are really must haves. I made mine from a wire spool. I just bought a bb "lazy Susan" (everybody know what that is? like 2 circular plates with bbs between them) and used one plywood shoulder of the spool under the other shoulder. Works great. The middle of the spool is a cardboard tube and I throw scraps in there or my PEX cutters. Do this!
- Know what you are doing! understand water hammers, the effects of service loops, sizing, difference between home runs, trunk and branch (no), and sub-manifolds. Know about recirculating hot water systems, instant on hot water etc. What PEX expander to buy is the wrong question.

I did my shop sink with one of these https://www.amazon.com/dp/B0BJZ9CJCQ?tag=atomicindus08-20
Worked fine for me. Watched more than a few YT videos.

Is this like the Vevor people were talking about? I don't have one of these, but it scares me. I do this work hanging off the side of a ladder, one handed. YMMV

Not sure about the Vevor one, there are bunches of these on Amazon. It was $70, two hand operation. I didn't have a ton of connections to make, just a sink w/ a small under-cabinet water heater.
I just used Apollo pex A at home, worked like any other pex I've used. Just went pro press -> Pex adapters and ran up to my new fixtures tho.
When I was doing this for work, all we used was Uponor or Sioux Chief, but Uponor is tough to get atm hence me using this Apollo.
Went and helped my buddy do a house a month back, they are up to 5 Milwaukee expanders, and all I ever used. Would recommend them.
Try running it in -30 degrees F, those are the days that I knew I was not staying in this field
Instead of 6-7 clicks of the expander you'll need to do about 13.
FWIW I never used an uncoiler and did a lot of water lines, just need to know how to spool your roll and feed it out, but its annoying at first.
Also, you shouldn't have a ton of fittings imo. Lets say you have a 3/4" to a far bathroom, just chop in Ts and send them up through the plate if in the wall, or through the floor if coming up in a cabinet, and leave them stubbed out long.
Then just like 1-2 fittings to make your final connection.
Long sweeps like this, leave it like 3-4 feet above the floor, done.

PEX-A is quite a bit more flexible and less likely to kink than any other type. Also, kink repair is ONLY acceptable in PEX-A. You absolutely must not heat PEX-B or C like that.
That’s not significantly cheaper than a used Milwaukee. I’d just buy that. I looked at a similar Vevor 20v pro press. Like you, I saw good reviews for it. And it was $300 vs $1200? for the Milwaukee. But I do t have many copper joints so I may just sweat them.
