Just a good wireless charger; it does its job. The only downside, which most other users also mention, is that you have to find the exact “spot” where it makes contact for charging. Perhaps I expected a little more from Samsung in that regard.

I have the Samsung Galaxy S21 Ultra which supports wireless charging and fast wireless charging.
I have disabled fast wireless charging and it charges at 15W instead of 25W.
On slow charging, it takes 4.5 hours and on fast charging, it takes 2.5 hours.

I noticed that with slow charging, it also discharges slowly!

You plug it in at night to charge and in the morning it is ready.
It will ask for charging again in about 10 hours.

For a long time, I charged it with a cable and a 25W charger in 1 hour.
In 6 hours, it needed charging.

It's great, I got it to charge my phone, the watch, or the headphones. I would like a faster charging, but the product is not responsible for that

I charge headphones, a mobile phone, and in the past, I also charged a Samsung watch. For the mobile phone and headphones, I use the left position; the Samsung watch would go on the right with a magnet and sit perfectly. Unfortunately, the right side is only for products with a magnet like the watch; otherwise, it's difficult to align. Other than that, it's very good, with the fan keeping a good temperature. It immediately catches the wireless charging, even through cases, etc. I've tried it on a Nothing Phone 1 and an S24 Ultra, as well as various pairs of headphones.

4 stars because they could have been made with faster charging speed e.g. 45w instead of 15w

My mobile phone (S23) has not charged 2-3 times, even though I left it charging all night (there was an indication that it was charging).
It charges slower, but this is expected.
It does not charge my watch (Samsung Gear Sport) at all, but it recognizes it and charges it for about 2-3 minutes and then the function stops. When I get a new watch, I will come back to give my opinion.

I use it to charge the galaxy s22 and galaxy watch 4. The problem is that when the phone is charging, it makes a quite annoying noise at random times during the charging process, especially when it finishes. I tried to observe if it comes from the fan, but I can't figure it out.
