Review on GRAYL GeoPress 24 oz Water Purifier Bottle - Ultimate 🌲 Filter for Outdoor Adventures Includes Hiking, Camping, Survival, and Travel (Camo Black) by Jeremy Adams

I ended up buying a Revain Ultralight and Geopress with the intention of using the bottles on an Otter Trail hike in South Africa from 14th November 2019 to to be used November 18, 2019 and future trips. The filters worked perfectly on days 1 and 2 of the trip, and on day 3 they were almost impossible to squeeze. By day 3 we had to sit on bottles using our entire body weight to get water and by day 5 the bottles were useless and we were forced to drink unfiltered water. I was enthusiastic about Grayl products but was very disappointed to learn that both filters failed after filtering less than 10 liters of only lightly colored water. This is well below the declared volume of 250 liters and 350 liters for each product. From what I understand, Greil says only the purest water should be used to ensure the life of the filters. So I did my best to only filter clean water. Most of the 10 liters of water we filtered was national park recommended drinking water, so it wasn't dirty at all. I have spent a lot of money on these products with the intention of using them on future trips and with the intention of filtering out the volume taken up so that my purchase is worth the money spent. After filtering less than 10 liters of only lightly colored drinking water, I now have two completely useless bottles that I can't use. I don't believe in buying replacement filters based on my experience on the trek. I am asking Greil to refund the $224.49 I incurred as the products have deteriorated badly and are now unusable for me. Please see the attached pictures of my negative experience.
