The bottle case is well-designed, and I could pick a water bottle smoothly. The tools attached to the case are very convenient, and I loved it. However, one day, I noticed the tool part disappeared midway through a long ride. I am unsure why it was off because I confirmed the screw was tightened before heading out. Since I did not have a backup tool, it was problematic. Also, I cannot find a replacement tool part. I recommend having extra caution with the screw part and/or putting a backup tool if it is a long ride.
