> 3 dayThis is a great invention. I always struggled to dry the inside of my hydration bladder. This little gadget does the trick in no time. It works amazingly well!

> 3 dayMan, I appreciate cool new inventions, and I want to support a small business. But after trying this a few times in 2 different brands/sizes of bladder systems, it just doesn’t really work much if at all better than just propping the bag upside down with a big plastic spatula or kitchen tings inside. Magically sucking the remaining moisture out of the tube that stays on the bag was a big draw...but it didn’t really do that. Appreciate that it’s compact, easy to insert and doesn’t look as janky as my kitchen tool method. And maybe for $8 I’d get a couple. But just can’t justify the price for the so-so performance.

> 3 dayThis works so easily and effectively. Ready for use the next morning. No more struggles with hanging my hydration pack on whatever is handy and trying to keep it open to dry.

12-06-2025Yes, this will dry out your water container/bladder quickly, but it made it smell like rotten eggs and now I cant get the smell out!! I was so excited when I saw it was dry, then I pulled the BonDry out and the smell hit me like a ton of bricks. I can confirm that it was the BonDry that created the smell because we have two bladders, and only one dryer. The other bladder which air-dryed is totally fine. Super disappointing.

Greater than one weekThis is a fantastic product. Love this and can’t do without this anymore. I use this several times a week for my hydration bladder. Makes drying so easy and complete. No need to try to keep it pried Open or upside down.

> 3 dayI wasnt sure if I was just throwing money away. It actually worked. Left it overnight in the hydration bag and next day it was actually bone dry!

> 3 dayI have some off-brand reservoir with a pretty small circular opening. Ive tried other reservoirs or drying systems but it always just collapses on itself. Until now, Ive been drying it by leaving it on the counter for several days, propped open with a combination of kitchen utensils and the tubing. My Bon Dry came last week, I tried it for the first time on Sunday and I swear it was dry in under 4 hours. Because of the opening I had to bend it in half to fit inside, but it still worked. Im so excited to get my counter space back!
