Review on WILD MAN Bike Bicycle Bag: Waterproof Phone Mount Bag for Android/iPhone 6.5”, Touch Screen Holder, Bike Accessories for Adult Bikes by Marvin Short

I like this phone holder and case. What I don't like are the phone holders on the steering wheel. When overcoming bumps on mountain bike trails, the rigid mount vibrates too much. This one dampens vibrations and also holds everything you need, keys, wallet etc. My son's bike doesn't have a bottle cage. The bag is perfect for a 20oz water bottle. The only thing is that the back of the holder tends to slide to one side or the other on the bike. Don't fret too much. I took industrial tape and taped it to the bike frame and bag to prevent this from happening. Now it works much better. I have one on my bike in my son's bike.
