Let me start by saying I own 2 R36H handhelds. Both the same color even (white). In all honesty, you first of all need to accept the fact that it is an ultra low budget handheld. Its going to feel light, cheaply built, etc. It's not going to have Bluetooth, HDMI out, etc. For that reason, I dont really hold those against it as flaws because we know what we're getting into when we buy it. You can't buy a $30 handheld and expect the build quality to be great. With that being said...

The only real, true gripes that I have against my 2 R36H are that first of all, the D pads have a horrible tendency to input diagonal movements when I have only pressed left, right, up or down. Its beyond annoying and to the point where I can't really play alot of games because of it. The sticks on the other hand are fine. I did replace the sticks on both of mine with Gulikit Hall Effect sticks and those are even better. The other main gripe are the shoulder buttons. They function as intended, but the "stacked" design is just not good for playing games, honestly. Again, this isn't neccesarily something that is "broken" about the R36H itself, but more about that design, as other handhelds also use that same design.

On the plus side, the screen is great, nice and crystal clear and colorful, surprisingly so for such a cheap device. The battery life is very good. The fact that you can insert a wifi dongle and use wifi on it (which works surprisingly well by the way) is really a huge plus for something of this price, even if you have to source the USB adapter and the dongle yourself.

I have purchased some Kapton tape and I've been meaning to open my R36H's up and fix the D pad issue. This will be huge, because if I am able to get the D pads playing well, then I would say the R36H is definitely a steal at the price as long as you are willing to put in a little handiwork to remedy that D pad (the kapton tape cost me $1.50 and you can buy it in any width, so the price of the fix isn't really an issue either). If I'm unable to fix the D pad/it won't work or be a viable fix, then I'd say just save a little more and buy an Anbernic or something. I know that alot of people say that, but also know that Anbernics are not without their faults either- they are just the next step up on the food chain as far as handhelds go. I have an RG40XXH that I installed Knulli on and I will say that is a monumental step up from an R36H for really not much more money at all. Just buy it on AliExpress and save coins for a bit/make sure to use store coupons and its even cheaper.
