Having purchased the Travel Well Pocket and been initially impressed with it I decided to try out its 'big brother'! As both purifiers use the same basic filter I thought that having a degree of interoperability would be advantageous - especially as I was travelling more and more with larger groups - groups larger then my little Travel Well Pocket could manage. With my Travel Well Pocket consigned to my Emergency Kit (given it's advantages in weight and size) I gave the Travel Well Trekker a thorough testing whilst travelling around Europe. It performed much better then the Pocket version, which was to be expected, however having trapped my finger for the umpteenth time with each stroke of the pump and having yielded slighly less purified water then initially anticipated I did find it hard to love this bit of kit. After a while I developed a bit of a 'knack' in using it - however it really proved itself later when I combined it with the Playtypus Filter Kit where I fitted it between two Playpus bags, hung it from a tree over night and waited for sweet purified water to be delivered drop by drop in the morning. Today this little piece of kit gets used whenever I'm overnighting it with a group or I'm setting up a base camp. I'm fortunate that I paid about half of the price advertised above as I'm not sure I'd be recommending it as highly at full price.
