I’ve had this filter for years, and it has always worked perfectly for me. Easy to use, easy to clean, and easy to pack. I tried to buy one for a friend recently on rei.com. The website said low stock, so I bought it, only to have my order cancelled, stating they were out of stock. Anyway, excellent filter.
When I know my water needs are not great I like bringing this because it is quick and light. Even
some parts are fragile but the filter is very convenient
