Rated 1 out of 5 by from Terrible Looks sleek and has a nice spacer inside for keeping a phone in place. However, this bag started falling apart for less than 7 months of light usage. The velcro is glued on and the glue starts to delaminate. Terrible construction. Definitely not designed by anyone that rides a bike. I'll probably have to throw it out in the next month or so. Oh, by the way, it may keep your items dry in a light sprinkle but don't count of items staying dry in a downpour. Calling this item a "drybag" is an insult to drybags. There are lots of similar products (often called "bento box" bike bags) that are much better at similar prices. This product is a black eye for Topeak.

Rated 2 out of 5 by from SHOULD have read the reviews... Found this bag while looking for a replacement of my triangle bag that was too small to hold a smartphone. Plenty of potential but... 1) While the bag is the right size the straps are much too long for road bike tubes and the placement of the tiny anchor points required modifications to the straps. I tried several mods and still had issues with a flopping bag. Totally unsatisfactory. 2) Interior is quite functional and the cover protects the contents (when it is properly positioned). 3) This bag has been in use for about three months but had minimal exposure to the rain so I haven't seen the deterioration referenced in other reviews. Bottom line – The instability makes this bag unusable so it will be returned.

Rated 1 out of 5 by from Flimsy construction I'm a regular commuter and bought this for my iPhone and wallet. It's waterproof enough, but the velro contact points were only glued on -- not sewn -- and didn't last long. I fixed it by super-gluing a strip of REI's excellent velcor banding, but when that fails I'll toss the whole thing out. A shame, really, becuase it's a good size and water resistant, but it shouldn't fail so easily at this price.

Rated 2 out of 5 by from only for show If you are into doctoring up a product then have at it! For small enough tube sizes, this bag's straps do not fit (which includes a fair amount of road bikes). I'm not even sure if there's a mountain bike that would be bulky enough for the overly long straps. For this price, I'd expect it to be perfect and fit in all of the right ways and not have to be hacked. It however would fit the bill for me if it could be secured to the bike.

Rated 5 out of 5 by from Perfect! Holds all my necessities. Perfect for stashing snack, keys, credit cards and phone. Even has a moveable and detachable interior divider!

Rated 1 out of 5 by from Terrible design. Returned. First off, the straps were far too long to fit any of my bikes, and sense the Velcro only goes half the length up the strap, I was unable to double wrap it to make it tighter. It is designed to sit atop your main pipe, and butt up against the stem, however, with its "waterproof" design (the lid just overlaps the main body, deterring water from pouring in, supposedly), it is awkward to open and close without loosening the straps. Returned after a couple days.

Rated 5 out of 5 by from This bag stores all of my essentials I was looking for a triangle bag that stored under the top horizontal bar and the vertical seat bar, but was unable to find one. I was very reluctant to purchase this bag because I felt it would be in the way while riding. I settled for this bag and now I really like it. The straps are long enough that the bag does not have to be in the way of the stem and yet you can adjust it to be stable and stay up when it is loaded. It is really easy to access while on a ride and there is a soft, removable divider inside to protect your cell phone from your keys. I am very pleased with this purchase. I read some other reviews that say it does not stay upright when loaded, this is not true if it is adjusted correctly on the bike. It is a very useful bag and is waterproof too. The cost is a bit higher than other bags, but it is a quality bag.

Rated 2 out of 5 by from Doesn't mount well Can't get the velcro straps to a position in which the thing stays upright. The strap around the post is near the bottom of the bag so the top falls over. Always tipping over, although stuff hasn't fallen out.
