I'm really on by this as it is inconvenient and unattractive: - The diameter of the clamp (to turn the knob) is too large and hardly keeps the shower which is in standard size - Although the color white appears on the photo, it is actually yellowish and really ugly on a white bathtub
The only positive that I would give (hence my 2 star) is the power of fixing the suction cup, which rib.
