The top is very slippery, and your phone can slipp of easily, but if you modify the charger case it won't slip, the lights are very good at indicating if the wire attached to the wirless charger isn't sending power, or if you're phone is charging or not. Overall 4 stars
Charges our Samsung phones and our iPhones. Charges quickly, from 20% to full charge in about 2 Hours give or take a few minutes. I like the green light ring that changes to green while charging. Great deal for a quality charger.
