PowerWave 7.5 vs 10 Charging Stand

Have some of you had experiences with both of these chargers would like your thoughts?

If you didn’t care about the USB ports on the 10 would you get it over the 7.5.

Do you know if there’s been any issues with the 7.5’s cooling fan failing prematurely?

I think both chargers are great. I’d get the PowerWave 10 just because of the extra ports lol
