Good for chinese/hong kong sellers. Bad for us. I got same treatment. I was on Alipress trying to buy a real CPAP EBMpapst blower which is actually pictured for first several pictures on the auction page. I got generic brand blower. Intended for special experiments.

This is what you have to tread very cautiously. Virtually all of these items are chinese junk but genuine surplus parts are rare.

Best advice is just buy sundry parts like screws, connectors are fine. Anything beyond that, shop everywhere else that are not chinese sellers.

Cheers,
