These work well. I thought it would be nice to have an extra.

The meter lets you know when the urine part of the toilet needs emptied. Prevents any chance of over flow. I was skeptical, but it works. A

Thank you so much for creating the urine canister lid with membrane, it was much needed for I that part had fallen out of my van and was therefore lost forever. I was so excited when I heard that you were making replacements. Thank you for taking care of your customers and God bless you all!

Way more convenient than huge industrial strength trash bags!

After using one that used water in a waterless area it is the best!

Great little addition to make sure you don’t have than unexpected overflow. Easy install and works as described

Nice that the membrane closures are available. Nice that they work so well at making this toilet odor free. Not so nice that they don’t tell you they need replaced every few months. Wish I knew this when I ordered the toilet, as it would have saved me the $20 shipping fee.

I no longer have to worry about how full my pee jug is! This is the best thing you can add to your toilet. The days of overflowing pee jugs is over!

Very happy with our new compost toilet for our camper.

As a full time RVer, who uses my Trelino toilet as the only one in my RV, I was looking forward to trying the Urinometer. I however find it hard to see what the level is and it only becomes obvious to me that it has risen when it is about to overflow. For the cost of this little invention I was hoping for so much more. I don't find myself trusting it and therefore am still checking the level the old way. I probably would give it one star but I don't like giving negative reviews and I know you probably put a lot of work into the design.

PS My soft close top mechanism recently failed. Is there any replacement that can be purchased for that?

The Urinometer eliminates the anxiety about the urine container volume. I tested with water & it works great. I no longer have to keep lifting the seat & pulling out the container to check the level.

I love this toilet! It’s easy, compact and simple to use. Very happy with it!

Looking good, easy install.

Our Trelino has been great on our western US camping trip with our teardrop trailer. Easy to use and clean and the coir we use eliminates smell. Nice to not have to walk 100 yards to an outhouse.

I love our Trelino toilet and one thing that I've always wanted was some way to know that my urine tank is full before making the horrid mistake of overflowing into the basin. So when this launched, I ordered one immediately. I run the red plug in my toilet and normally when you remove it to pee, there's a slight odor that escapes, but not bad. With the Urinometer installed, there's a HUGE odor because it's literally breaking the seal into the urine tank. When you look down on the Urinometer, you can see the opening that's there at all times. So yes, you now know when your urine tank is full, but the expense is that now your Trelino stinks

This is a great product. It is comfortable and very portable . Clean up is a dream.

We took the urinometer on its first trip in our van last month and it worked exactly as advertised. It saved us from a potential overflow situation! It is a bit expensive for such a simple device, but is worth it to give peace of mind and reduce the chance of unexpected messes to clean up.

I havnt used it yet but it in there waiting for the first " ladies" no men allowed...

Perfect. Small, sleek, stable, odor-free and easy to use. Thank you!

This spare solid container and the whole toilet is just a piece of junk. Made from the flimsiest plastic. The latch to remove the containers from below stick when trying to open. It does not smell and the top lid operates properly but I wish I would have saved my money. We have gone back to the bucket and it is much cleaner and simpler. Now our trelino just sits there taking up space.

So far it has worked as advertised. I had a porta a potty but how can you keep that clean? This seems easy to keep clean. It tucks under my bed and I never leave the van if I have to go.

Our replacement membrane was easy to install but I noticed that the flat valve surfaces (where the urine enters the tank) do not close completely. There is a small gap which allows the odor to escape.

not for me

Looks good but expensive for what it is and somewhat flimsy
