Bike Citizens Finn Universal Smartphone Silicone Bike Mount

I have a normal smartphone (Samsung S8). Once you have mounted the phone it looks fine...no problems there. However once you start cycling down a normal London road if you hit any bump or hole the phones shakes and vibrates in a way that causes concern since there is nothing to restrain or hold the phone in place.2 weeks on...please see my edit - i have upgraded to 3 stars

Superb design and like a built in shock absorber too. Easily stowed in your pocket when you're parked up.

Lovely product, item arrived a day early. would recommend product to anyone!

Never again! Elastic strand broke after 18 months of just OCCASIONAL use of strapping my medium sized phone to the handlebars. Purchased alternative 'cheap' ones for a fraction of the price that last far longer.
