After a year of use without any particular difficulty as a second controller to play with my son, the left joystick broke on the L button, it doesn't reset anymore, its battery doesn't last long anymore, it started to have some small drifts (rarely), and the right joystick only works when it wants to. Don't be stingy, get an original one to be done with the problems

I will speak as a beginner on the switch. Incredibly comfortable with great analogs! My hands are big so the genuine ones are a bit difficult for me. I got these and I felt relieved! It takes a little longer for them to connect compared to the genuine ones, but their analog, the grip when they are connected to the switch, and the scandals on the top buttons, I can say that they eliminate this small disadvantage.

The only complaint is that if you have them connected, you can't put the switch in the dock. And it doesn't fit in the case. Other than that, it's fine!

Update on the rating. After a month of use, the right joycon suffers from a very, very bad drift to the point where you can't play. Prefer something else.

For its price, it is really nice! I would prefer it to cost 60 euros and be of slightly better quality (like the joy cons) in terms of the plastic used and the LEDs. Other than that, it fits perfectly on the switch without any gaps or that protrusion that other "better" brands have. It has the classic gyroscope which works great, and I prefer the rumble from the two large motors it has over the 3D of the joy cons. They are very convenient to hold, even in table top mode. However, when you connect it to this black connector to make it look like a remote control, the LEDs bother me a little. But the most annoying thing is that when you play with the lights off, because the plastic is probably a bit thin, the light shines through the controllers. So, I simply opened them up and put insulating tape on the LEDs to cover them and also on the back, because their light passes through the circuit board. Now they are almost perfect. (By the way, they charge on the switch, so don't be alarmed by the fact that they have a USB port at the back). You will need a small screwdriver if you open it, and be careful not to cut any cables. The screws don't need to be tightened too much because they go into plastic.

I bought this product a while ago and I was torn between this and the hori. I had been eyeing it for a while and finally decided to get it. So far, I think I made the best purchasing choice. The response is really good. The battery is excellent. It's lightweight and quiet. If someone is considering it, I believe it's simply worth buying.

I bought the product as a replacement for my basic joycons, as the left one specifically developed the well-known drift issue after three years of use. Although I purchased it with doubt, I ended up finding it superior to the original.
- They are slightly heavier than the original joycons and are designed with curves that provide better grip.
- They function wirelessly, as stated in the description, not only in handheld mode like most third-party joycons.
- They charge normally when attached to the switch while it is charging. Just like the originals. However, the box includes 2 USB cables for their charging.
- It has the vibration function normally.
- Unfortunately, the home/power button requires a prolonged 10-second press to turn on the console. Slightly annoying until you get used to it.
Overall, it is an excellent alternative to the original joycons and lacks nothing. I highly recommend it.

UPDATE, 10 MONTHS LATER:
The right controller simply died. Only one of the lights faintly blinks, but it doesn't function or charge.
