We use this monthly in our septic tank and have never had a problem! The price was very good compared to competitors! Really like the fact I could order it to be shipped at sale price without shipping and handling and received in 3 days!

It really does what it is supposed to do. We are glad to get this size package and the price was right. Great for the 1955 farm house too. Thank You Sam's Club!

Sams Club has the best price for Ridx. It is the only brand I use for my septic. I tried a few other brands long ago but came back. I don't ever want to try another brand (as long as Ridx doesn't change).

Bought 3 when they were on sale, month or so later found several hundred flour or grain beetle looking bugs all over the storage area. Opened the box and saw them inside as well. Beware storing these boxes, if purchased use right away.

I thought it was 5 single separate doses not 5 doses in one Box and you have to estimate when you have poured 1 Dose. Also the Box had been damaged and was taped.

Very good price versus buying one or two doses at a time. Makes a lot of sense for us who use this regularly.

It works. Hard to determine the doses even with the markings on the box. I now have moths.. they flew out of the box!

We have been buying and using this for years. We have been 12 years without septic problems so that speaks for itsself.

We've bought this several times over the years, and it never fails us. We never have problems with our septic system as long as we use Rid-X.

Have used this product for several years successfully, WM price was good as is the product
