Review on ROCKBROS Saddle Bottle Bicycle Waterproof by Dave Hersma

First of all I didn't appreciate the durability and strength since I just received the goods. This design is really well thought out, including a pocket that has enough space for your tube, CO2 cartridge and valve, tire holder, multi-tool, etc. The water bottle holder is also well designed, not only fitting but also good elastic cord that can be wrapped around the bottle for safety when riding. BUT, AND THIS IS A BIG BUT, the mounting mechanism is poorly made. There is a bolt-on bracket on the underside of the seat that attaches to the rails. To this end, the bag has a built-in plastic rail that slides into the mount and "snaps" (there is a flexible latch/protrusion that you can press to release the locking mechanism and remove the bag). Putting the water bottle in the holder tightens the "stop" restraint on the rail and everything is fine BUT when you pull on the water bottle to take it out the latch/tab comes off with very little force and the bag comes loose is suddenly no longer there. firmly connected. The only trick I could think of is to remember not to pull straight up, but to rotate slightly and pull up so as not to dislodge the latch. It's manageable, but not ideal or acceptable. Rockbros should redesign/reinforce the locking mechanism.
