I do have 3 needles (0,12, 0,20 & 0,40) and had a hard time with mine. I figured out something that isn't mentioned in the manuel of H&S Infinity. I knew the needles have tabs on the back according the size. 1, 2 or 4 tabs. But the nozzles have marks too. 1, 2 or 4 rings.

So, combining a 0,20 needle with a 0,15 nozzle (not 0,12) wasn't a good idea. Not by purpose.
@acker_pascal One of those aspects that we need to be aware of with young players buying the cheaper multi-needle/nozzle sets which don't have (based on my experience) no obvious 'pairing' markings (other than in the individual item packaging). 2/
@acker_pascal Interesting I didn’t know that either, thanks 👍
