I was skeptical about how well it would stay put on bumpy trails, but it holds my tube securely until I need a drink. The quick detach is smooth enough that I can grab a sip without fumbling around.

The magnet is way stronger than I expected — it holds the tube tight against my jersey even on rough gravel. Clipping and unclipping for a drink takes half a second now instead of fumbling around.

Didn't realize how much I'd notice this little thing until I used it on a long ride. The magnet snaps the tube back onto my jersey every time without me even looking down. Detaching it one-handed mid-climb is way easier than fishing for the bite valve.
