Pros: Efficient

Cons: Loud**

Recommendation: This product does what it should do. It dries out the bladder of your CamelBak. I have never had an issue with it not drying or a malfunction. I drain out all the water from the bladder and then hook this little thing up and let it sit overnight. Done. The bladder is dry and no fear of mold or smell. Also, I have never had bad tasting water or smell from water after using this product. Would definitely suggest it

Pros: It`s a good idea. Eventually dries the bladder.

Cons: Very loud, does take a long time to dry and you need to periodicaly shake the pac to get all the water out

Recommendation: I cannot recommend it. However if you are one who does not clean out your pack and needs something to get you to do the drying then this works.

Pros: small and compact. Multi-uses. Dries packs better and faster.

Cons: Loud like a hair dryer.

Recommendation: If you hate mold and fungus because leaving your wet gear out to air dry isn't working good or fast enough, better spend less than $40 on this little gem. My camel pack has no more yukky tasting water in it anymore and my shoes don't smell like that creek I last rode through.
