0) Controversial cross. Someone says that it is terrible, someone says that it is almost the best among all gamepads, I rather belong to the latter. It is indeed very easy to press diagonally, but I would not call this a disadvantage, but rather a difference from what everyone is used to. Apparently, Nintendo wanted to do something like an 8-way d-pad, but in the shape of a traditional cross, and that's what they basically did. I got it. But if so, it's worth keeping in mind.
1) The + and - buttons are exactly the same shape as the "Home", and it's almost impossible to find them without looking, but they are next to each other. For some reason, no one has mentioned this yet [at the time of writing], but it can really become a problem, especially after joycons.
2) Another design flaw - the indicators of the controller number are located at the end of the device, that is, looking at it from above, you cannot understand whether it is controller No. 1 or No. 2 if you have two identical procons. In the joycon grip, these indicators are visible from above, which looks much more logical, but here they did it somehow strangely.
3) Glossy front insert, most likely, will be scratched into the trash in a few months.
4) There is no normal charging indication - when the cable is connected, the front light turns red, and when charging is completed, it simply goes out, and it is impossible to understand whether the gamepad is charged or the power has simply gone out. Why it was impossible to make the indication a separate color or even use the light bulbs used for numbering is a mystery.
5) Of course, the price in is prohibitive. With all the pluses of the controller, it should by no means cost more than the DualSense, and even so much more expensive. I don’t know at what rate the prices are calculated in the 2022 branch of Nintendo, but 70 euros is by no means 7500. At the same time, for this price, in addition to ergonomics, there are no unique features relative to standard joycons (such as petals, turbo buttons, or something like that).
