Your products came highly recommended by a friend and I have been looking at it for ages. Soooo glad I finally bought one, and ended up buying one for my partner. I drive an old Land Rover so the vibration is a fact of life but my phone holder is the BEST!

My husband and I love your product, we have in the past used cheaper products but found they always fell off the window, I am happy to say yours never does, I love the range of movement for positioning the phone exactly where I want it. Awesome product I’m glad I spent the money.
