This is an awesome piece of little gear! I used a Sweetwater for years because it was the lightest and fasted pump out there and it could be sort of field cleaned. Although it has a few drawbacks when it broke it was over and a new cartridge was almost as expensive as the whole unit.
So when I saw this little monster I thought how good could it work? It is even smaller and even lighter than my Sweetwater. When it boasted the fastest pump on the market I had to give it a try (well my other pump had broken again). After a whole season out, it is faster, lighter and tougher for sure it didn’t clog once and most of all I never dreaded pumping water once all season.
The bottom line is no matter what you are using turn it in and get one of these! Unless you are a tablet using snob…
