The fillers didn't do much for my phone in it and I couldn't even turn it on with gloved hands, it mounted well on my one inch stock bars but when I opted for one and a half inch T bars the mount wouldn't fit so now I can't even use it on my motorcycle...I have yet to try it on my mt bicycle
This works as it should. I have been using it for 3 years now. Keeps my Phone dry. Just can't push buttons through the cover and get a response from the phone.
