    Millwaulkee back pack sprayer base.

    This shoots a nice size stream about 30' up, a lot more than any good pump up that I've owned.

    Wrong part but i was able to disassemble and use pump with my mounting plate . Works well . Pay attention to the shape of the mounting plate . I was unaware that there is two different shapes . One wont work with the other

    Takes the work out of spraying.

    This sprayer looks & work as new. The straps are much more comfortable than my old pack pack sprayer.

    Poorly engineered

    Tank leaked right out of box. Unusable first time I put water in it. Got to looking at reviews online and discovered this is a very common problem. Quality tool company putting out second rate product. Very disappointed.

    Great quality

    Little on the heavy side but it is well made. Plenty of flow settings for every use.

    Only used it once so far, it seems like its going to do everything I need it to do.

    A little heavy, but no pumping is nice to get your chemical sprayed.

    Leaked horribly out of the box!!!

    I t leaks terribly. I tried to tighten the little screws on the bottom. Wasted me bottle of Treflan! I’m not a happy camper. I’ll try to take it apart this weekend to see if I can fix it before going through the hassle of returning it.
