[EX Q]: so, this thing is like a big fat crochet hook designed to grab the inside lip of the jacuzzi ball and pull. Which would be great, except that it's ONE QUARTER INCH TOO SHORT. Maybe Kohler changed their design to make it deeper, or something, but this tool is next to USELESS for removing jets from my tub. Instead of the ball lip, all you can "grab" is the sloped ledge inside the ball, which with a LOT of persistence and side pressure might eventually get the insert to let go. We finally "modified" the tool by melting portions of the stop-ball away, making it more functional and much less pretty. Caveat Emptor.
[EX A]: negative

[EX Q]: First I must say, I have never received anything I ever ordered from Amazon arrive in this condition. The pictures are worth a million words. I’m disappointed.
[EX A]: negative

[EX Q]: This device is life saver. We have a water leaking inside of my wall in the kitchen and I just use this device to know where is the water leaking came from . And after I test it we found out that the leaking is from my kitchen sink drain pipe. This is amazing. Highly recommended.
