I had the old 450 bottle. Security was second to none. But with the bottle sitting under my down tube it would get absolutely coated in dirt. Buying this I swapped over the magnetic mechanism from the 450, and now I have a dirt free water nozzle! Absolutely love it. Just ripped some rugged downhill the other day and the bottle was still there, as expected. This is class leading for security and cleanliness, in my opinion. Water comes out faster as well. Absolutely worth the 17$ upgrade price.

I enjoyed your original fidlock bottles very much but the new design with the flip top is so much better. It is easier to drink from, and easier to close. Nice design!

Keeps the dirt off the mouthpiece. Wish they designed it so you can flip it off easier. Sometimes need 2 hands. Also the bottle is not really a clear black. It is a frosty gray.

Great water bottle.

I know the bottle will be there when I need it. The new design is awesome. No dirt/dust on the tip
