I can't fully express how well this toilet works. I was a little aprehensive about living full time with a composting toilet. I had done a fair bit of research on the topic in preparation for living in a tiny house and this one seemed to be the clear leader.
I had so many concerns: would it have an unpleasant odor? Would it be difficult to use? Would it require constant cleaning? What about installation? Most importantly, HOW WILL I LEARN TO AIM??

Well I am pleased to report after two weeks of full time use that all my concerns are calmed.
Firstly, it has no discernable odor, even when the lid is lifted or the upper portion is lifted partially when removing the liquids bottle to empty it every other day or so. Even when in use it us less odiferous than a standard flush toilet because the little onboard fan is constantly whisking any odors right out the vent hose.
It is not difficult to use, just sit and go. Open the trap door before a solids deposit of course, but otherwise just do what you do naturally.
Installation was easy, this 50 ish woman with slightly above average handy person skills did it in 15 minutes.
Cleaning is simple if you spray down the inside of the bowl with a water and white vinegar mix after EVERY use and perform a minor wipe up with a paper towel (which you then just drop into the trap door) if you have a particularly egregious contact mark. Which leads me to AIMING, which is not even a thing, just sit down comfortably. This thing is so well designed that unless you have some wildly divergent anatomy that I can't even imagine, it is a non issue. That trap door is right where it needs to be. Just remember to open it first. And if you are a dude, just sit already, it's ok, nobody is judging you.
As for emptying things, the liquids bottle is easy to remove, cap, carry and dump. I have't got to the point of emptying the solids chamber yet ( I used coir fiber available here on amazon as the composting medium) so I will update if it is anything other than as straightforward and simple as all the other aspects of this product. If you want lots of details on that there are several good youtube videos on the topic.

The brilliant design, heavu duty construction, super simple installation and stellar online support makes this worth every single penny.

I like this toilet but for almost a thousand dollars I would have changed a few things. I added no-see-um netting to the intake and exhaust of mine and also replaced the stock .07amp fan with a .15amp fan that seems to blow 4 times the amount of air. I was worried about back draft on my mobile application. Additionally I had to buy a mushroom vent that didn't come with the kit. For the price I paid everything should have been included. It does work though, and my poop doesn't stink. Clean it with a little vinegar and you're good to go.

So far so good! We installed the head on our sailboat. It was a pretty painless. We also installed solar vents in the dorades above the head. It's working great! Great to have those smelly hoses and tanks gone.

Great improvement to our motorhome, now we can dry camp for an extended time without going to a dump station due to a full black water holding tank. Where we stay all we need is to resupply the fresh water and food. ( nobody needs a black water tank to shorten the stay )
If you can't drain your gray water where you stay your black holding tank can be put into gray water service which gives you two gray water tanks.
Think about all the fresh water you put into the black water holding tank, fresh water is for drinking and washing.

Water is for drinking. It is rapidly becoming too scarce to waste on flushing toilets.
The out house, it turns out, was a much better idea than we realized years ago,
This is a lot smaller than an out house, and you don't have to dig a big hole.
Getting as intimate with your poop as you must to empty it, is good for your sense of personal humility.
You will also have an abundance of very good compost for your roses.
There will be somewhat more water for people. to drink for a little bit longer into the future, if you get one of these.
For five stars, it would have to empty itself.
