It’s hard for me to assess this clearly, because I’m not sure myself which opinion I lean toward more. On the plus side: the whole thing looks really good and can easily be attached to a backpack. The reservoir itself can be removed easily, and the tube can be detached, which makes cleaning and everyday use much easier. On the other hand, the smaller reservoir really holds very little. I managed to pour in a maximum of about 800–900 ml, and that was almost to the brim, yet when screwing on the large cap, some liquid still spills out. As a result, the capacity is quite small for an accessory of this size. Another issue is that the reservoir can leak if the cap is not tightened completely, literally all the way. Even so, I wouldn’t say it’s a very bad product; it’s just that everyone has to judge for themselves whether it will suit their gear and needs.
