Like >>12027383 said, vertical devices aren't terribly comfortable. It still sounds like a good device at its very low pricepoint, but personally I prefer something like the RG40XXH more compared to its vertical equivalent. About the same width/thickness as my phone with its case on, but more comfortable to play older games on due to being wider, and I think its worth it for how cheap it went for on sale (paid about 70 CAD so probably 50 USD). Probably not more powerful though for an up to PS1 device but may have slightly better build quality to make up for it.
As for buying the cheapest handhelds consistently on something like Aliexpress, they have pretty frequent sales. Just check not only the product but the store ratings as well. I unfortunately can't speak on not getting duped by any clones but I think there's only really there's only the one vertical model with a 3.6" 480p screen with the D-pad on top.
