Familiarity: I've put it through the wringer
I accept some of the shortcomings of this from other users. I'm pretty happy with it actually as it fits snug under my seat and transfers from bike to bike pretty easily. It is limited in capacity, I keep the "heavy stuff" , 2-3 CO₂ cartridges, inflator, multi-tool in this and it's compact. I also use a strip of velcro below the BOA wrapped around the roll and seat rails to keep it totally tight, I hate stuff moving around under my saddle when climbing or sprinting. Spare tube and mini-pump still go in the jersey. I've had no issues with durability. So for me it's been a good solution to keep some weight out of the jersey without having a massive bag under the seat. As others have said, if you want to stuff everything in here then this one is too small and you need to go for the larger version.
