This Magsafe Car Mount Charger from OHLPRO is very well built. The three adjustment knobs operate smoothly and do not require a lot of effort to lock the adjustments in place. The knobs have no sharp edges so they don’t dig into your fingers when using them. The arms all stay in place where you adjust them and do not move again until you readjust. Overall, the mount feels solid and nothing rattles due to loose tolerances. The VHB adhesive used on the mounting pad holds very well on the wood vernier surface in our car. Hopefully it will still hold when our summer weather comes. The Magsafe charging head is all aluminum except for the pivot ball in the back and looks great. My S25 Ultra with a Magsafe case is held tightly to this mount with the strong magnets. I have not noticed any shifting of the phone even on rough roads. I was surprised to see that there is no charging cord or power adapter included with this mount. Usually fast-charging mounts include these to assure that you reach the charging rate that they advertise. One thing to note, if you are looking for interchangeability between this charging head and other standard 17mm ball mounts, this ball is undersized at approximately 16mm in diameter so it does not fit other standard ball mounts. Overall, this is nice, well-built car mount charger, but it would have been nice if it fit the standard 17mm ball mount size.
