Query: Is This Thing On?

I saw a lot of negative reviews about this item, but there were also a lot of positive ones, and it looked like those who had trouble had not followed the instructions properly--so I gave it a try. I should've listened to the bad reviews. I never put the tester in any liquid. I followed the directions exactly. I tried it in different soils, some of which were fairly dry, and some that had just been watered, some with fertlizer/some without. The indicator never moved. It stayed in the exact same spot no matter what type or condition of soil I tested. When I pick it back up, the needle wiggles, so I know it's not stuck in place. It just doesn't work. I can stick my finger in the soil next to my plants and know more than this thing can tell me. Save your money.
