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.
