These are customer returns
for parts or tinkering. So not necessarily running machines unless you fix a few things. Not something to buy as your first 3D printer.
However, they are inexpensive at $59 with free shipping, especially if you can't pick up a $99 Ender 3 V2 from MicroCenter nearby.
I would mainly see this as a base for a project where you want to convert the printer to something else, like one of those Ender 3 belt printer conversions, etc. Or just use it for parts.
The $69 Ender 3 Pro could also be converted to a Voron Switchwire for example.
There are also some
refurbished [creality3d.store] machines with a 10% discount, which are checked and should work out of the box.
Ender 3 specs:
- 220 x 220 x 250 mm print volume
- Bowden extruder
- Prints PLA, PETG, ABS, TPU
- 0.4mm Nozzle Diameter
- Printing precision 0.1mm
- Movement speed up to 180mm/s
- Heated print bed
- 270W Power Supply

"These machines are all returned by Comgrow Amazon customers. The condition of the machine may be open box, used, show signs of use, missing parts, etc. This includes, but is not limited to, clogged nozzles, scratched hotbeds, scratched profiles, and spotted displays. Please consider carefully before purchasing."
You're right that this is a total gamble. The missing parts bit is the only concerning thing. A single missing part could be around $5-$20 to replace. The amount of time that it takes to replace that part is a totally different issue. Anything beyond the scope of something like replacing the plastic extruder would be considered a wash in my opinion and you'd be better off buying one at $99.
The only checkout method is paypal, so if you get a totally busted printer, they will see the "Printers From Amazon Return-[No Refund/Return]" and likely shoot down any attempts to get a refund.

I've heard plenty of stories of how it's often just a bunch of binned parts thrown together for you to sort through. If any major part is bad, then in the end you may end up spending what a brand new unit with warranty would've cost you.

The refurbished Z1-10W 10W Laser Engraver for $152 seems like a solid deal for a powerful entry level laser engraver. A new Z1-10W is $300ish. Its usually $200 just to upgrade to a 10W head upgrade (no frame/motors).

Not saying that's what's happening here, but it's definitely a common scenario for manufacturers and suppliers.
I can't really say it is the most practical purchase I have made as the concept is way cooler than the actual product IMO. There are just only so many plastic things and dodads one really needs. They are probably great for table top gamer minatures I would think but most of the things I printed ended up in the trash a few weeks after I made them and their novelty wore off.

All of the parts in these things are orderable. It would be blind bad luck if you bought 2 and both had the same parts missing or broken. That being said you probably would be better off just getting a refurb unless you just enjoy the tinkering part.
Operator error is probably the main reason for these being returned, there not just a plug in and play item ( they can be) but more often than not you will need to spend some time adjusting belt tension, maybe the filiment you ordered needs a higher or lower temperature to print well, maybe one of the wheels was put on just a bit too tight and causes some friction that makes all the prints turn out bad. The guys that just watch a Youtube video of a shill saying how great it prints out of the box and the customers find out they aren't quite that user friendly yet. Their printer doesn't print perfect out of the box so they think it is broken and return it. Or they do a couple prints and the nozzle clogs and they don't know how to fix it. Or even more likely a print sticks badly to the heated bed and they destroy the bed taking it off ( been there done that) but if that happens on your first print people might just decide to return it in leu of buying replacement parts and spending the time to fix it especially with Amazons free return policies.
So the short answer (or not) is probably you could easily buy 2 and build a complete one, now how much time it takes you to take the thing apart and put it back together 7 times to figure out that stepper motor 3 is skipping every 3rd spin or is it a bad wheen or loose pully causing the bad prints is a different story! If fixing things is a fun project for you then it may be a a good project for you to get into.
