Review: is what it means - is what it means
Review: AWESOME PRODUCT! - These are great for cleaning the black tank out. I really appreciate these. Read the directions. Use as it says although I usually put the pod in the toilet, add HOT water so the stupid skin from the pod dissolves. And then fill the black tank up. The pod skins are disgusting and I don’t use pods for anything but this brand only comes in pod form. It works. Bubbled up. Gets the chunks out.

### ⭐⭐⭐⭐⭐ Effectively Cleaned RV Black Tank Sensors
*by M***N on 29 August 2023*

Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying. We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for.
