Digest-it classic works!

We were using the orange tabs and had some odor. My husband researched and found this as highly recommended so we tried it. We have been using it for a month now while staying full time in our 5th wheel and are very happy with the way it works. We no longer have intermittent odor, black tank seems to flush clean, and it is economical to buy at Walmart. This is the only black tank product we will use going forward and we highly recommend it.

Good product

We've recently bought a camper/RV. You don't need much of this product so you do get a couple uses out of it. Seems to be working. I try not to put as much toilet paper in the black tank as possible.
