It's not just the CAMCO drop in's. We've had several members report that they "drop in the packets" and have found them not dissolved, partially dissolved, intact and plugging (caught in) the slide valve, or gumming up the sensors. Some say they got partial "odor control" (in other words, they could smell the orange) and others say they've never had a problem with the drop in's.

If I remember correctly, the recommendation was to tear/cut the packet to be sure it does release the contents into the holding tank.

To me, if I were going to do that, I'll just buy a "liquid deodorizer" and pour a little of it into the toilet when needed or desired.
