Query: The plastic gave up after a year of light use

I used this mount on my mountain bike. It was a capable mount, had a decent grip and held the phone - until it didn't. The plastic clamp fixing it to the handlebar just broke in half. I live in California and store the bike indoors so cannot blame extreme temperatures, this is just poor product design and not the right material for the job. For the next mount, I will go for a metal clamp, less expensive than replacing a phone.
