Yeah with 3mm jets, you can’t be stingy with the water, but I found 2mm jets splashed all over the shop. (No pun intended)
Most of the water was bouncing off the glass, therefore less flow down the glass for a rinse.
3mm on the other hand, it’s amazing, like a nice waterfall down the glass and no splash back. It’s like pouring a jug of water down the glass to rinse 😎
I just could not get on with fan jets, took too long to rinse. Not enough water weight.
Each to their own though 🙃
