I bought this for occasional use on my bike. It is easy to put on and take off - with an elastic band and a hook. Once on the pole, it's tight and hard. It stretches well, fits my Galaxy S10 phone and holds it securely, but you can remove the phone and mount from the mount if you need to leave your bike. First, it's really cheap (I paid $3), but it works very well. ! There is no reason to spend 4 or 5 times more on another. Update: I forgot to mention that the phone holder part only slides out of the mount when it's in landscape (landscape) mode. Didn't get it at first and struggled to turn my phone off in portrait mode (doh!)
