"I like the assembly. However, very disappointed that spare replacement filter cartridges are not available. Makes me think that the product and it filter are being discontinued and phased out. Have written and inquired about this but have yet to be answered."
"If and when water filtration is necessary, it provides our small group an alternative to go along with the individual lifestraws and Sawyer minis"
"A++++. Excellent product and highly recommended!"
"I haven't used it yet but it seems well constructed. the filters looked legit too. need a chance to use it"
"Great thing to have in the cabinet!"
"Great item. Adds some volume to water supply during an emergency or on a family camping trip"
"Really like this filter. Priced right and can provide my family emergency drinking water for a year if needed. However, I purchased this product previously and it came sealed in plastic. This time around it is in cardboard which I get is better for the environment but not better for long term storage."
"I bought this for a gift for my son for Christmas. Strangely when he opened it up he said "oh - this is what my girlfriend wanted us to buy!" Uncanny. He was very happy to receive it although honestly he didn't understand why he needed it - she did!"
"Wonderful products, high quality and fast shipping! Bought the Family 1. 0 for emergencies to be prepared as well as an original LifeStraw. I bought the Go Waterbottle to use daily so I don’t need to buy overpriced bottled water when I’m on the road."
"I probably will use for emergency only. Makes me feel much better knowing I have these for my family should the water become contaminated!"
