Really good
Scent: Orange, Size: 30 Count (Pack of 1)
Using them in our 36' TT. Easy to use, works fast and eliminates odor. Good value for the price. Compatible with any camper, rv. We like the freshness and value. Can't speak to safety. Package quantity is great.

No smells!
Scent: Orange, Size: 30 Count (Pack of 1)
These work really well for us in our camper. Our tank holds around 40 gallons. After dumping the tank I drop one in the toilet and flush for about a minute to add water to the tank. Then. Everytime we use our camper in the summer (2 or 3 times a month) I drop in another tablet in the toilet and do the same thing. This has worked great and we never have had a problem with smell! The box usually lasts me a couple of years. Definitely recommend.

Product great. Delivery not so much.
Scent: Lavender, Size: 30 Count (Pack of 1)
Product works fine. But having it delivered by Amazon in just a brown bag caused the plastic container that holds the product all in the bag. This really need to be shipped in a box. Aleast I can use the product and will have to store it in a Rubber made container.

Our go-to for RV tank maintenance – reliable
Scent: Pine, Size: 10 Count (Pack of 1), Scent: Pine, Size: 10 Count (Pack of 1)
This has become our go-to brand for maintaining the tanks in our 5th wheel camper. We’ve used several products over time, but we keep coming back to this one because it’s dependable and does exactly what it’s supposed to do. The drop-ins are super easy to use—just toss one in and you’re set. We’ve had no issues with unpleasant odors while using these, even during longer trips, which makes a big difference when you’re living in close quarters. We trust this brand and their products, and it’s one of those items we make sure to always have stocked before heading out.

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.
