I bought this kit to clean a 100 oz Antidote bladder. I am very unhappy with it.
First, and most importantly, the hose brush is too short. This is a bizarre oversight on the part of Camelbak. The brush does not go all the way through the hose, so it just pushes dirt around inside it.
Second, the kit comes with no instructions. Presumably there is a correct way to use the too-short brush, but I sure can't figure out what it is. For such an expensive kit, I'd expect explanations of how to clean every nook and cranny of the bladder.
Finally, it seems that the hose would drain better if it was held straight, but the hanger does not do this. If the kit was less expensive, this would be forgivable, but at this price every detail should be taken care of.

This product makes cleaning and drying your Camelbak very simple.
Another reviewer complained that there weren't detailed instructions on how to use the product. While for the price there probably should be, the online video was very helpful.
My only complaint is I wish it included a second hanger, or that Camelbak would make this available for separate purchase as we have multiple camelbak's for the entire family and don't need additional brushes.
Other than that, I enjoy the product.

Not sure why Jay Hiker had bad things to say about this kit. I am quite happy with it.
Yes, the nozzle brush should be longer but if you clean your equipment right away, it shouldn't get so dirty that you "push dirt around".
And, there is a product use video on the description page on-line... very easy to use and explained well.
The cleaning tabs have the tendency to leave an "aftertaste" if you don't rinse the bladder extremely well, so that would be my only other CON, but too hard to put into a short answer.
