This is the most useful item I have purchased on amazon for my bike. I decided to make full use of the good weather and cycle in London. I wanted a GPS/Bike Computer for my bike so that I can keep track of the routes, get directions, calculate distance, speed etc. Instead of purchasing a separate computer, I decided to download "cycle meter" on the iPhone (its an excellent app by the way). So the next thing I was looking for was an iPhone holder. There are many choices available on amazon but the reviews and the price made me choose this one and it was a very wise purchase.
The Design:
From the pictures I thought it was going to be a monster and might look hideous on the thin handlebar of my road bike. But it looks just fine. It has a very nice finish and everything is absolutely perfect. It comes with removable foam pads of various thicknesses so that you can position your phone perfectly inside the pouch (the phone wont wiggle around). The pouch locks-in to the bottom clamp with a 'click' and will not come off even if you're riding through an earthquake.
Ease of Use:
It was a piece of cake to fit the bottom clamp. It has a rubber grip that makes it sit nice and firm on the bar, a hand-adjustable screw (no need to look for a screw driver) and a 360degree rotatable top (to which you fit the top part that contains the phone). You can operate your phone through the front plastic film and when parking the bike, you can remove the whole pouch with the simple push of a button.
The only negative side I can think of is that, if its raining heavily(pouring down) you might get some water inside (normal London rains are not a problem). But then again, you wont be riding through such heavy rain.
Over all its a great and very useful piece of equipment. It looks more expensive than it actually is. I strongly recommend this to every single biker out there.
