Buying used vauto with replaced motor?

[fishfinderG]

I’m considering buying a used vauto that has had its motor replaced recently. It still shows the old number of hours from the first motor. 

Should this be relatively safe, or is buying a used BiPAP machine with a swapped motor a bad idea? I’m pretty sure I can buy it with Paypal protection.

Thanks!

I think if it’s the right price it’s a good deal. The blower motor seems to be the culprit when these machines start making that whining noise. So if you have a new motor , basically you have a new machine.

I’m waiting on a blower motor from Aliexpress now. It will go in my a10, to replace a whining motor.
