Loving it so far
I’ve only had this about a week but I like it so far. It has a hook that grabs the vent blade and is very sturdy. It also has a part that slides up and down. I realized after a few days that can be tightened as well. Makes the phone even more still. There is a small button on the right that releases the arms that grab the phone. I didn’t see that noted on the instructions so mentioning it here so no one pulls on them like I did a few times.
As long as this doesn’t damage my vent, I will be pleased.

I sanded a table I am working on to refinish and it came out perfect and smooth .. great value for your money for sure , was very easy to use .. I have only used it once but plan on using the the buffer on the stone pillars after I refinish the marble ... love having two kind of handles .
