My used spulen catch can feels like a dream all of a sudden.
Hose #20 takes the cake for value.
That price is outta this world for a recirculating catch can.
Any decent can setup can be turned into a recirc one fairly easily via the dipstick and a oil restrictor from a turbocharger
Keeps the PCV/Catchcan from overpressuring and lets the can drain into the low point for a maintenance free setup
