Question about SodaStream Duo Megapack XL

There are simply 2 types of cylinder. Our previous one didn't fit. I find this one much better as it has much more carbon dioxide in the water. No, it doesn't drip, so to speak.

According to what I have found out myself, the (red-blue) cylinders are special and no others (not even from Sodastream itself) can be used. I have not observed any dripping.

If you think it's great that the stuff flies around your ears at some point? - Otherwise I would use what is really compatible!
