This review is specific to using the charger with a Samsung Galaxy S23+ in a Rokform magnetic case. So far it's the Only wireless charger I've found that works with the case. It does only charge at the 7W level not 15. But since this charger is designed to work with an iphone and not a Samsung device I didn't knock a star off for that. Overall the charger seems well made. Strong magnets and rather heavy. It does get quite warm but my phone has never alerted for overheating or reduced charging speed.
