Lots of fakes on ebay now. The products, and the vendors too.
Back in 2020 I ordered some MH-MINI-360 (MP2307-based) buck converters. I needed them kinda quickly so I filtered by Australian location on ebay, and to hedge my bets I bought 4pcs each from 3 different ebay sellers figuring I'll use these in hobby projects in the future and they're cheap. Plus, whichever one arrives first will let me keep prototyping.
None of them arrived for 3 weeks, which was frustrating.
Then I got 3 identical packages in the mailbox, on the same day, with almost identical labels on them (including the sender's address) but different "ebay seller" IDs.
I'm very selective about what I buy on ebay these days, usually the fake vendors sell a ton of unrelated products. The real ones are quite obviously an online presence of a real store, and they're much better.
