This item fits just right on the ashtray. I didn't do any processing. Very good!
Overall the product seems to be of good quality. It doesn’t fit great unfortunately, it was very loose in the recessed area where it’s supposed to slide into. I had to use a few pieces of double sided tape so it would fit snug and stay in place. The biggest issue is how slow it charges, or really at all. My phone immediately recognizes it and shows it’s charging, but it never actually charges. I’ve been in the car for multiple trips now ranging from 15 min to 45 min and after being on this charger the whole time the battery never moved even 1%. I have an iPhone XS that is fine on multiple wireless chargers at home, just seems this one is extremely slow when it’s labeled as fast charging.
