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.

Really a nice product!
Style: 15W Charger, Style: 15W Charger
I wanted a nice magsafe charge/holder for my phone and I tried this one and so far, it's great. Pros: - It has a really nice-looking LED behind the magsafe holder which glows nicely, as you see in the pic. - The plastic feels good, strong and (hopefully) not plastic that degrades and becomes brittle. - The rubber bumpers which hold it in place under the mount against your display seem well-placed. - It's fully adjustable between positions wherever you wish to mount it. - You can mount your phone either above or to the side of the display on any corner which provides nice flexibility. - I found it best on the upper right because on the left, the steering wheel obscures the phone and the two bottom corners aren't useful to me. - The little knobs work well to hold it in place and tighten nicely. Cons: - The only problem is how the design has the cable visible and sticking out when it could have easily been designed to integrate into the little arm so it's hidden. As it is, the ugly, out of place and avoidable USB-C cable is visible which I don't like. - You can rotate the holder to make the USB-C cable appear in front of the arm holder so it's less visible but it should have been avoided with a simple design modification and integrated USB cable for a more streamlined appearance. In any case, this is a nice addition to my Model 3 Performance to hold my phone while I drive, out of the way while still charging. Try one. M

Amazing iphone mount for Model Y.
Color: Upgraded Version - Gray
I was pleasantly surprised at how this phone mount worked for my purpose. I am a care driver and drive a Tesla Model Y. This mount perfectly fit the screen and my iphone doesn't come off even when I hit a pothole. The best part of this mount is the price. One cannot find anything cheaper than this. As for the function, this mount really fits the bill. Thumbs up!

Decent MagSafe phone mount
This was just an average MagSafe. Build quality is ok. The material, especially the plastic parts, feel cheap. The design is nothing to brag about. It can be mounted anywhere along the edge of the screen. Although it's marketed as for the Telsa Model 3/Y, It can be used with any cars with a tablet that fit's the dimension. I actually had problems installing it because I have a screen protector on and the added thickness resulting it the mount barely being able to squeeze it. Note the design prevents adjustments in certain mount positions as the end of the slider will run up against the lock nut. Magnetic strength is acceptable although I question the stability when the slider is at it's maximum extension with a phone mounted. Overall, it's perfectly functional but I would prefer something a bit more refined and minimalist.
