Smooth, strong, impeccable. reposition to get it just right if you are careful and keep it clean.
super solid. I really love the articulation this offeres. So much flexibility. Iphones natively may be limited in using the full potential of the wattage due to internal limitations on non apple wireless pads, but I'm pretty sure this is faster than the tesla chargers by a lot. the build quality and modern vibe are impeccable.

A great line of sight phone holder with a few flaws.
Overall this does the job and is priced affordably the pros and cons are as follows: Pros: Strong magnet Solid construction Great for line of sight Charges well Cons: Charging cable is not long enough to route inside my car holder tends to droop down slightly with my phone on it (Pixel 7), not so much that it's failing but just not holding it's set position
