Since I got it, I have changed the position of the mobile phone many times, the light around it flashes and the phone does not charge... I think it is one of the purchases that I regret, although it is a very practical device.

I use it in the mornings at the office so that I don't have to plug and unplug the cable every time I get up. It charges relatively quickly, although the time doesn't bother me since it sits on the charger almost all morning.
iPhone 11 with a not very thin case, charges fine unless it's very out of place.
Satisfied with the product.

VFM Quite good for its price, as long as you put it in the right position. The charging time is almost the same as a regular charging with the cable, 45 to 60 minutes more. But when you put it at night, there is no problem, it is ready in the morning. The charging stops automatically and rarely stops at 99%, it doesn't heat up at all (neither the phone nor the device), it is quite good. Ultimately, if there are any negative comments, they will likely be based on the buyer's expectations, but let's not forget the saying, "every device has its own luck."
