STJ Conversion Kit

I know that there are lots of things that say that they're quick, easy and only take a few minutes. Most of those things typically take several hours and usually have me using some pretty foul language by the time I get done. The STJ conversion kit isn't like that. You just unscrew the spigot that originally comes with the jar, then screw in the PumpToys converter. The silicone seal makes using the STJ nice and comfortable. There are also lots of online reviews written by folks who got paid or got free products. I bought the kit with my own money and haven't been compensated in any way.
