Coolest wireless charger design I've seen
I just gotta say that this is the coolest design for a wireless charger, looks kinda futuristic. Now how well does this work? Amazingly well and truly easy to use. It is adjustable, stable and much safer for everyone. I really like this charger.

Wow that light color ring is annoying
There is no way to turn this color light off. I don't even know why it has to have a light at all. I suppose it is to tell you it has power. But the light could have been something that momentarily turns on and then off as you place the phone on.
I'm a DIY'er and I'm going to find a way to take this apart and disable the light. I'll report back if I'm successful.
The good news is that this mount is identical to another one I have except for the magnet charging section. I'm talking it is identical down to the knobs and metal arm so it's generic in that sense. They only changed out the magnetic section. This type of mount holds well to the screen. The charging speed seemed adequate. Not terribly fast but not slow. Wirelessly charging is always slower than plugged in.
The supplied USB cable is braided and feels like quality.
See attached picture. This mount is not something you'll necessarily want to use every time you drive. Therefore the color ring is annoying.

SLEEK EXTENDABLE SCREEN MOUNT
HIGH SPEED TESLA MAGSAFE POWER
i picked this up for my Model 3 to see if the 25W Qi2.2 charging actually lives up to the hype during my daily work week.
✨ The CNC aluminum build is top notch and feels much more robust than the flimsy plastic mounts i have tested. It's a piece of cake to clamp onto the corner of the Tesla screen and the metal arm matches the interior aesthetics perfectly. The magnetic hold is strong enough to keep my phone secure even when i am taking sharp turns thru my weekend adventures.
✨ Performance is where this thing shines because it actually delivers the 25W speeds without overheating. The built in cooling fan is a smart design choice that keeps the temperature down during long drives. i can hear the fan if the music is off but it's barely noticeable and definitely worth it for the consistent charging speed.
✨ The RGB lighting adds a subtle glow that makes it easy to find the mount in the dark without being distracting. Having the extendable arm is a big benefit for finding the perfect line of sight without blocking the main touchscreen. It's clearly a well thought out solution for any Tesla owner who wants a professional grade charging setup.
THE VERDICT
This is a exceptional piece of hardware that delivers real world results for high speed charging. The combination of active cooling and a sturdy metal build makes it a first class addition to my car.
'As a 35 year veteran of the computer technology industry, I offer informed and experienced perspectives in my product reviews.'
I will update this review if anything changes within 1 year.
★★★★★ (5 Stars): A 5 star rating indicates the product meets my expectations for its purpose.

Works great. Perfect position
Grip and charging are great. I like the position because it doesn't block my view or the vents
