Bests & Worsts Reviews from Amazon

This product is hands-down the best filter out there! I bought mine at Bass Pro Shops for $19.99, but it happened to be one of the older 3 year shelf life straws, which could explain the price difference(Was manufactured in May). It takes a second to get the water flowing, and its not easy to "blow out" the water as it recommends, but this thing works great! My favorite feature is that, when it can't filter water anymore, it just STOPS LETTING YOU SUCK WATER THROUGH IT. Amazing, right? No guesswork...just get a new one ever 3/5 years, and use it till it stops working. Note: Its a little hard to blow water out, but not impossible. If you find yourself blowing and not getting ANY air out, its cause it sealed itself(however that works) and isn't gonna let any more air pass through, you've gotten enough out already. Don't waste your effort trying to get the last few drops out, it won't happen.
