Anyone ever use a Cage Rocket?
 

My Wife gave me this thing for Christmas called a Cage Rocket. I had never seen one before. It's a little compartment that fits into your water bottle cage. I tried it out the other day on my commute. Pretty cool, 'cause it's easier to get into than a behind-the-seat bag. I put my sunglasses and energy bars in there. Only $10 US.

Anyone else ever use one of these things?

You know, that is a very good idea. I used to use an old gatorade bottle (wide mouth) to store my keys, etc. in. But this is much cooler. Thanks!

Very interesting idea. I'm bookmarking this.

Where do you put your water bottle then?

In my hydro pack if I'm mountain biking. On my road bike I have a saddle rail bracket, so I have four cages on that bike.
