It is a weird device that sucks air from the cassette when the blade is opened, sounds good in principle not so sure in practice

We had one on last van

The air has to be taken out from the top of the cassette, so there is something else to fiddle with when emptying cassette

We also suffered the ultimate price, not sure that ours was properly fitted, but drove with full cassette and ended up with brown streaks down side of MH as contents tried to escape through air vent

Another gimmick I would not pay for if not already fitted (y)

To save asearch........a SOG is a basic 12v fan which extracts fumes from your cassette, passes the fumes through a carbon filter and sends it merrily on its way to the great outdoors.

Works well but the contents of the cassette dont get chance to decompose and stink to high heaven when you empty out.

It negates the need for chemicals so can be emptied in any kind of sewer drain....chemicals should never be emptied into a septic tank system as the chems kill the good bacteria.

SOGs are brilliant things that enable you to avoid using Earth-destroying chemicals. Also a great topic of conversation here: http://www.motorhomefun.co.uk/forum/threads/sog-toilet-emptying-bio-hazard.95904/page-4
You will be left in the cold if you don't have one. :) Put one on your Christmas list.

Rumours that the manufacturer is bringing out a turbo version to deal with constipation are I think just wishful thinking - unfortunately.

Never felt the need for a Sog, depends how you use your loo. If you want to open the valve and plop straight into the tank then it might help. I'd rather plop into a bit of water, then close the lid and activate the valve, No smells at all, maybe mine doesn't smell. :)

SOG is great to let the whole world that your using the loo! You flush, and when the pump is running, it turns on a fan, thus pulls air from inside the motorhome, down trough the toilet, down into the poo tank, across the wee and poo, and pumps it outside, over the next doors dinner table (if your loo is on the drivers side) and out under you awning if you loo is on the caravans door side!

You take a perfectly good Thetford toilet, drill holes into it, bodge into the wiring and cut a hole in the door, just to stink the high heavens out when you empty it, and stink out your awning or next doors dinner every time you have a wee (do use if your easyily embarrassed lol) oh yes and the simple slide in action of the cassette, is compromised as you have to hook up and disconnect the fan to the tank every "in and out" action.

Formaldehyde by the way can be used in chemical treatment plants, we didn't think it could be when we built our camp site and had special tanks installed for chemical toilets. Only to find that the problem is the high concentration of solids in cassettes and holding tanks that can cause treatment plants problems rather than the formaldehyde.

Of course none of that is a problem with a SOG as you never get chance to build up solids as the smell is so bad you have to empty it every day ::bigsmile:

I guess that's why Thetford don't add it as standard!
