I also hate YT reviews and prefer written reviews any day, but with these Chinese handleds you really need to make your choice smartly, I mean, it is not like you could go at your nearest Walmart and look it and touch it and try it out.
In the best of the cases you can buy one overpriced at eBay or Amazon for a quickly experience, normal case scenario you buy it straight from China web page or AliExpress and deal with the longest shipping methods, and in the worst case deal with ugly warranty process if all go wrong (which can happen, so buy smart and use PayPal or something to protect yourself).
I recommend you RetroGameCorps YT channel since he’s the best one when we are talking at reviews of this niche gaming sector.
He goes from all the relevant aspects of the handheld such as touch and feel, power/performance, battery life, “pocket ability” and portability, comparison with relevant models, height, weight, emulation showcase, you name it.
He also divides his videos on parts so you can quickly select what is relevant for you.
There are other great handhelds reviewers, but no one can beat RGC!
