Bests & Worsts Reviews from Amazon

I bought this water filter months ago and used it all summer long on my horse packing trips. Its really light, compact and does produce very clean and good tasting water. But, I had issues with the pre filter plugging up even in a reasonably clean water source and ended up using it without the pre filter. Considerably reducing the life of the main filters. So I only gave it 2 stars. Within a day after the review posted the manufacturer must have read it and immediately contacted me. They let me know that there was a an engineering issue with my original filter and that they resolved it and wanted to send me a brand new replacement, totally free of charge. Not only did get a complete unit in 2 days, but also a spare pre filter. Best customer service I have ever encountered.
