I bought it and sold it again not long after.
As already mentioned, I also found it difficult to find the right position; with 2 it was practically impossible. To be fair, I have to mention that I have my S23 in a leather case. No problem with inductive charging in the car, for example, but on the EP-P it is.
I'm back to the "cable solution" for at home.

Samsung Galaxy S25 Ultra is definitely not a problem, we have not yet been able to test other new products from Samsung.

Not sure, we dont use it anymore and we always used with older models. However, I would not recommend it. If you don’t find the exact position, it just wont charge. So you spend a lot of time trying to find the correct positioning and sometimes it moves a little, you think its charging but its not

I use an S22 Ultra and it works very well. (I use it at night with a Hue timer 2-6 o'clock)
Can only recommend it.
Best regards CP

Hello, I bought it a year ago and it is compatible with the Z-Flip 5 and Z-Fold 5. It seems to me that it should be ok with all smartphone models with induction charging. Only the power may be a little lower than with the new chargers and so the charging time may be slightly longer than with the new generation chargers. To be checked if necessary.
