Stem Injector Kit
Stem injector worked very well (though I won’t be able to see the results of the treatment until next year) - worked as intended, easy, ergonomic. Not a critique but am not sure why someone wouldn’t use the sharp needle for everything instead of the hand drill method. But I’m very satisfied with the product.

Well made!
I haven't used this gun yet but did a trial run with water. Its a very sturdy design and looks like it will be able to take some abuse. We are excited to use the 2 guns we ordered.

Worked very well .
I was a little frightened handling pesticides. I took full precautions. The Injection system worked easily and very safe. So far the injected stems left up have all turned brown. Some stems did produce some, but the laves were deformed. But mostly all growth had died. I missed some plants. But I read you can use the Round Up until fall to be effective against Japanese Knotweed
