Bought as need 88 keys with zero budget. From memory, there has what it takes connectivity level (pedals). Many sliders / knobs.
Touching correct, it's lightweight Fatar low end but hey why not ...
Memory convoluted but comprehensive manual.
It is very finely configurable level knobs.
Screen readable but winded.
The big problem: the level of finish is catastrophic. Obviously everything is bad plastic, the screen is unresponsive and is generally ugly, but especially the bore holes of the front is rough, some important control buttons are momentarily stuck in use (you can also see the wiring in places) ... Annoying in the studio and on stage unusable. Hopefully it was a defective series, this is the first time I saw it on a keyboard, especially from a recognized brand. In general it's very cheap, and it shows especially on a 88 keys.
Conclusion: you have what you paid for, a proper 88 keys at this price it does not exist, they had to try to fill a niche but given the quality tradeoffs it is not worth the trouble.
That said, it has another advantage besides the cost is its weight, that of a 61-key about (again from memory). So if you need to look at all costs a very light 88 keys to carry, very cheap and with great control panel is, and you are ready to make concessions on ergonomics. Otherwise, go your way.
ADDENDUM: I just saw next to my view an advertisement for a SL-990 PRO from the same manufacturer, this is typically a much better investment for exactly the same price ... it's heavy, it comes straight from the 90's and there is no other controller that the two wheels, but the quality has nothing to do. Proof, 20 years after it still sells.
