    • Fresh Camper, Zero Odor: A Game-Changer for RV Life
Scent: Orange Size: 30 Count (Pack of 1)
Camco TST MAX RV Toilet Treatment cubes have been a total game changer for our camper. From the first use, they made a noticeable difference in controlling odors, keeping the entire space fresh and comfortable. The cubes are incredibly easy to use—just drop one in and you’re set, no mess or measuring required. Even during hot weather and extended trips, they consistently break down waste and prevent that dreaded tank smell from creeping in. I also appreciate how compact and convenient they are to store. If you’re looking for a reliable, hassle-free solution to keep your RV smelling clean, these cubes are absolutely worth it. ... show more

    • A Must-Have for RV Life – Works Well and Smells Great!
Scent: Orange Size: 30 Count (Pack of 1)
We have been using these Camco TST MAX drop-ins for our RV trips for years, and they are a permanent part of our setup. Options & Scent: I love that they come in different scents, though we usually stick with the orange. It’s a very pleasant, fresh smell that isn't overwhelming but definitely gets the job done. Bottle Size & Value: We typically get the 30-count bottle, which is a great size for several trips. The container is sturdy and keeps the pods dry and fresh until we need them. Performance, Softness & Leak Prevention: These pods are great because the outer "skin" is soft and dissolves very quickly once it hits the water. My husband handles the tank maintenance, and he's impressed with how effectively they break down waste and tissue. Most importantly, we've had no issues with leakage or clogs, which gives us total peace of mind while on the road. Safety: One of the biggest selling points for us is that they are formaldehyde-free. They are safe for all septic systems and RV dump stations, so we have total peace of mind regardless of where we are camping. Verdict: Reliable, easy to use, and effective. We wouldn't go on a trip without them! ... show more

Review Image by Delilah Welch
Item works as it should, cleans toilet and makes bathroom smell good. Shipping from Amazon damaged the container, a few dropins were rain soaked and unusable. I was going to return item but it wasn't worth the drive of 30 miles to UPS store. I got this item on sale.

    • Not the best of scents for an RV Toilet Tank
Scent: Lavender Size: 30 Count (Pack of 1)
I don't know why I thought the scent of lavender would be great for my black water holding tank, but it's not. I'm sorry to say that I will have to return it. There's 30 Camco toilet 🚽 treatment packets in this container. All you have to do is just drop one of these packets into the toilet and flush it down into the holding tank. I am not saying that this product is not good; I'm saying that I will have to exchange it for a different scent. I won't know until I try a different scent, because I might be allergic to Camco's RV Toilet Treatment Drop-ins. The lavender scent put out such a bad smell, I couldn't breathe all night last night. I had to keep filling up my tank, waiting for awhile, and then dumping it all out. I had to keep doing that till the bad smell went away. So I'm gonna give Camco another chance, and try a different scent, and just go from there. I should have known better than to use a toilet treatment that had a perfume scent. I'm allergic to fragrant's, I have to use fragrance free laundry soap. ... show more
