It’s been modded, which is always a crapshoot. It could be a stellar printer, or they’re lying, or they think it prints amazballs, but has really low standards. Or it could be even more amazing and their standards are just straight up OCD.

From what they say, the mods are fairly common for creality printers.

It’s also super common to mod your printers, especially lower-end brands like reality.

I would suggest asking if they could do a test print- and give them the filament to do it with. Something like a Benchy won’t take too long, or too much filament. Also if it comes out nice ask for what they used as print settings.

If it prints well, 150 is a spectacular deal.

That said, I wouldn’t suggest entering non a used printer. Too many things to go wrong. (I’d also suggest avoiding the lowest end of printers.)

Used printers often require fixes that require you to be knowledgeable in to fix.

I recommend Bambu printers if you wanna dip your toes in the hobby. They’re locked down quite a bit but they just work. I think the A1 mini is excellent.

Like others have said, it’s definitely not “too good to be true” territory, but there’s so many things that can be wrong or not right with it that you’re much better off getting a new printer. Sure you might save $100 getting a used one but the chances of you spending weeks chasing a problem that you admittedly have no knowledge of diagnosing is just way too high for it to be worth it. For someone with a bunch of knowledge and experience this would be a decent deal, but so is a car with a check engine light or salvage title… could be (probably are) opening yourself up to way more headache than the money’s worth.

@BussyGyatt it’s a reasonable price, that’s an old model and the replacement goes for $289 brand new
