1. The sound is worse than that of the Yamaha 363 or 463. The speakers are small, they sound plastic, you can play, but if you want the feeling of something real, it's better to play on headphones.
2. The keys are a little more "loose" than on the Yamaha 363, there are micro-plays, creaks, etc. I can’t say that it’s directly critical, but if you play half an hour on one and the other instrument, then I personally got this feeling.
3. Regular music stand (iron bar frame) is simply no. Notes and sheets fall into it if they have at least some tendency to fold. Previously, in such designs there was a rubber strip - add. horizontal jumper, it somehow solved the problem. Now - either do not put it at all, or immediately put some kind of cardboard frame on it, or "" jumpers. In general - cheapening led to its complete non-functionality.
4. No LCD backlight. It is clear that the model is of the budget segment, but get ready to put an LED clip-on lamp on the music stand (here it will come in handy) or add some other lighting option. Otherwise, it is hard to read even in a normally lit place.
5. Sliding volume control is less convenient than rotary on other models. You can make the volume 100% with an unsuccessful light movement.
6. The body material looks and feels inferior to Yamaha.
