It's not worth the money,
Verified Purchase(What is this?)
I bought this RAM EZ-ON/OFF bicycle handlebar mount for Apple iphone 3G in summer 2011.
It took me a couple of months to get round to fixing it on the bike.
Easy to fix- just two narrow zip ties (would cost less than pennies to buy). Didn't seem very secure. I have used zip ties plenty of times on bikes etc. and I know they're tough- but they can pull out...I was not overly sure that I wanted to risk my iphone falling off.
The iphone sits in a casing with a big, four-pronged 'knobble' on the back. This knobble is pressed into a hole on the mount against the pressure of a spring, and twisted into place.
I didn't need to worry about the zip ties failing: On the third use, the plastic knobs on the four-pronged knobble sheared off as I used mild force to insert it into the mount.
I had not kept the packaging/receipt and had it a few months before use. I didn't ask for my money back- but don't waste yours.
This really is a rubbish piece of 'kit'. Badly designed, even without the shearing, and clearly not worth the asking price.
Phone vibrated a lot on the bike too.
