MSR Guardian Water Purifier
A very easy one to handle and has a strong structure. In the beginning, I had to pump a while before the purified water had its taste improved. Otherwise, I really enjoy the fact that I don't need to purge or clean the pump like on some other purifiers as there is an auto-clean system. Regarding Dwights' customer service, I had a great follow-up as one of the purifiers I bought was leaking. The case was solved in a few days!
