Actually the Zeenho TinySA was only a couple of dollars more and only showed 9 pieces sold. I'm not sure how accurate AliExpress sales numbers and ratings are? I made the purchase based on the

Checking beyond basic info, going as deep as possible, ESPECIALLY when the price is low is 100% must. As a rule you will walk away 99.99% of the time after checking (yes that is an exactly calculated
