What model respirator did you end up getting? Some of the cheap ones don't seal right and let stuff in. A good fit matters more than people realize.

Yeah, the printer thing is too real. I once spent an hour trying to write a script to auto-reply to boring emails, and it just sent "potato" to my boss. So much for coding magic.

Ugh, glad you figured yours out. Mine just sounds angry all summer no matter what I do.

Nah, that's just junk.

Ever notice how this caution with no-history sellers shows up in other places too? In my experience, it's the same with buying used cars or hiring a handyman, where no reviews means you're taking a big chance. @uma685 is right about trusting that doubt, because I once bought a cheap monitor from a similar seller and it had a huge crack down the middle. It's a pattern where avoiding the unknown saves you from real trouble later.
