Leaks like crazy wrote

If you fill it up with 4 gallons it leaks out the top, After about a year of use it started leaking out the bottom. I don't know how they get away with claiming this is leak free.

purchased three of these sprayers to spray various chemicals. 2 of the sprayers have failed completely (one in less than a month of use). the third is beginning to fail to hold moderate pressure after 10-12 months of moderate use.

A.M. Leonard: We have contacted the customer to help diagnose the problem.

The new Field King is much better in some aspects, but a little lacking in one or two others. For example, it holds slightly more than it's predecessor, and sprays better with less waste, but does not set as firmly when being filled. It must be strapped into the bed of a pickup whereas the older model when full stayed in place without straps unless you were driving over a bumpy road or pasture. I usually place mine in the passenger seat of my truck rather than having to fool with strapping. It feels more firmly in place on my person when all the straps are buckled, but it is more ungainly to put on as the shoulder straps are too short for ease of puting one's arms through. And I am only 5'2" and 184lbs. I can't speak to it's endurance yet as I've only used it for about 3 months but it feels slightly more sturdy than the older model which I used for over 12years. I spray for weeds at least every two weeks during growing season especially along concrete driveyas (1/4 mile)and on gravel driveways/pat
