Hi there. I buy cheap Wax Guards

[Alaniow]

I use the Signia Stretta NHS supplied hearing aids with replaceable wax guards which are pretty expensive
I discovered that TEMU the online store do wax guards (£9.00 for 40 guards) though they DO NOT mention Stretta
They do a 1.2 mm size which fits Stretta.
A bit fiddly taking out the old one but the new one snaps in fine
