First off, it didn’t even come with the charging chord, so I had to order another separately after it came. The product broke the fourth time i used it, the whole thing came apart when i tried taking my phone off. When it was working, it charged maybe 1% every hour. Definitely not the best choice in the category, look at other options

Super stable, strong magnet, fast, charging Tesla screen mount

Style: 15W Charger

This is a great item. It’s adjustable annd attaches firmly and no tape no adhesive. I’ve been using it for several weeks now charges the phone very fast.. The phone has never fallen off of it. Not even close. Highly recommend this item.

Works great, but included cable is too short

Style: 15W Charger

The cable included is only about 3 feet long and has a USB-a plug. Teslas now have only USB-c outlets, so the cable is useless anyway. If the cable were 6’ long and type USB-c, it could be tucked under the molding and hidden. I had to get another cable to complete the installation. I like this mount/charger because it is nondestructive - it doesn’t use tape or glue to install. The magnet is strong and it charges my phone quickly.

Decent but magnet isn’t strong enough

Style: 15W Charger

Unit appears well made and I feel like it minimizes any potential damage to the screen. For me, magnet just wasn’t strong enough and I wasn’t a fan of the cable - would be nice if product had clips for cable management or something to give it a cleaner install. If it wasn’t for the magnet issue, I probably would have kept. Returned.
