In fact, you have to straighten the part slightly from time to time. Tip: Apply a layer of adhesive tape underneath directly to the handlebar. I, at least, would buy the holder again. I appreciate simple solutions.
Very robust mount, but: tape or even better a strip of an old inner tube underneath! Protects the (carbon) handlebar, avoids unintentional slipping and allows slipping, e.g. in case of a fall, so that nothing is damaged!
