A Must-Have for RV Life – Works Well and Smells Great!
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!

Finally, an RV Toilet Treatment That Actually Works!
I’ve been using these Camco TST MAX Drop-Ins in my RV for a few trips, and I’m honestly impressed. The orange scent is pleasant — not fake or overpowering — and it actually keeps the tank from smelling up the bathroom between emptying. I’ve tried other treatments before, and most of them either fade too fast or don’t break down the waste and tissue well. These are so easy to use — just drop one in before a trip, and I don’t have to worry about odors or clogs. It’s made my RV trips way more pleasant, and even my kids noticed how fresh everything stayed. Definitely going to keep a pack handy for every outing!

Pleasant orange scent and it treats the septic system... BONUS!
We actually purchased these after a fellow RV camping neighbor/friend recommended them. I am so glad they did! The orange scent is pleasant but NOT overwhelming (which we appreciate). The scent lasts for about 3 to 4 days then starts to fade by about day 7. This is perfect for us because we hardly camp for more than 10 days... usually 5 days, on the average. We have never had any septic issues. But knowing that these also treat the septic tank and help break down tissue and gunk is a complete bonus!

work good and good Price
They work good. But not as well as the blue ones when it comes to hot weather and depending on how long your black tank sits. But I have to say overall they keep the smell down. If you’re not in a very hot environment these work very well. During the hot summer months you might need to switch up to a stronger pack. Or maybe double up packs but thats not very cost effective. I am also looking for cost effective options.

Not the best of scents for an RV Toilet Tank
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.
