If the store has a proper name, has been established for a few years and has 95+ user ratings it’s normally safe.

Stay away from stores created very recently.

That price looks legit, the PR2 was never expensive.

It looks fine…but I wouldn’t buy PR2 or any KZ for that matter. There are better options from better companies

If you’re going to ask if it’s a reliable source, cropping out the name of the store doesn’t help.

If it is gold store plenty of feedback, almost certainly legit though. That price is a “welcome price” for new users only, it’s another $5 or so off the regular price. And PR2 was never that expensive, I have seen them for around $22 in previous sales.
