I put a battery for my iphone in one side and run the cord to the iphone in its case on my handlebars--so for long rides using Strava or similar, I can not run out of battery.  The other pouch holds energy bar, and the waterproof cover keeps everything safe.

Pro-
big enough for phone liscence and a gu or about 5 gu's.

Con-
soft sided so it does not stay upright really well unless it has stuff in it.

but it is a good price

I am doing longer rides and a half ironman this summer and I needed something to hold my nutrition for the ride.  Fits well on my bike and the Velcro holds well.  Could do without the florescent green "rain lid"  cause it cuts down on aerodynamics.

Perfect size.  Phone, wallet and a power bar fit perfectly.

wish the velcro straps for the stem were longer.  I have integrated cables, and they dive into the from just behind the stem.  The velcro straps don't reach the stem with the cables in the way. . . have to velcro the cables to hold the bag on.  Other than that, five stars.  Good product.
