I too installed a cassette ventilation system about a year ago and agree that there is no smell inside the van at all from the cassette.
Outside the van is another story. Although the system comes with an external filter it does Jack you know what. Before someone says that the filter needs replacing, it was like that from day one.
The SOG and similar systems are great for free camping where your neighbours are parked outside of the "smell zone". No chemicals are needed and the cassette contents can be emptied into any septic without fear of contaminating the system. When in a caravan park where you neighbours are within a metre or two of your van the story is a bit different. This is particularly evident with angled drive through sites when the toilet cassette of your van is adjacent to the outdoor seating area, ie: the neighbours awning. In cases like that I have disconnected the cassette ventilation fan so the neighbours don"t get the "aromas' every time you use your loo.
I ask others with these types of systems to advise if they have experienced the same "aromas" outside their vans when the toilet is being used, or is it just that my crap stinks more than other peoples.
Agree with thomas. We were parked beside one in a caravan park other van on our awning side and the smell was horrendous. I would never inflict that on my neighbours and should be banned in caravan parks.All there doing is propelling your smells onto others.

I would like to know.

Robert,
Yep, I am aware of the smell of roses outside especially when just turned on for use.
But as a general rule its likely that except in periods of heavy use there's a slow leak of
roses that is usually not noticeable.
You can also get a whiff when others use the potty and your windows are open and a waft
can come in.
A failsafe assistance is to have a pressure sprayer with a mix of water and sodium PERcarbonate
under good pressure and use this as a pressure spray when some roses are clinging to the exit
of the bowl. Intelligently used this will mostly alleviate the necessity to flush with water and
thereby save your water supplies and not fill the holding tank so rapidly.
Sodium PERcarbonate is available online or use 3X the quantity of NappyySan VANISH.
I have a 1 liter pump sprayer and adjust the nozzle to a fairly narrow spray.
will keep the bowl nice and white also. $7 at Bunnings.
I use 1 teaspoon to a liter of water. 3 teaspoons of NappySan Vanish.
It sounds to me like a solution to a problem that does not exist for most people, and (believing those comments) the solution makes the problem worse than what it was intended to fix. A properly managed cassette toilet has no odour problem.
