Cleanstream Inflatable Double Balloon - Two Models?

So, I'm looking for a new nozzle and stumbled on to the fact that there are two models with similar specs but different numbers.

Does anyone have any idea why one is model RU710 and the other AD666? I've asked a seller on ebay with both to see what they have to say.

I will report back when I hear something!

One of them is most likely a Rusch....All the older posts where many comments could be found is now no longer...But the consensus was that the Cleanstream was somewhat inferior & of a short shelf life in compasrison

http://www.medtech3000.de have the double package (2 sets) on offer...see product link below

Careful those RU710 nozzles are 'cheap' knockoffs of the ones Klystra once had manufactured. Those cheapies won't last long. Buyer beware.
