it does warn about otex and tinnitus I read it to day.Pretty sure the warnings say don't use this sort of thing if you have tinitus
I know someone else who ended up with a perforated ear drum when her normal nhs doctor syringed her ear wax so even the professionals get it wrong sometimes
Think Specsavers do suction removal rather than syringing, don't have any bad stories about that, lol. My dad had this done a couple of times
I can find the irrigation machines as used by the NHS and they are not too expensive but cant find anythat spec savers use. I did take a punt at a cheap pair but they were that bad I told them to collect them and they said keep them and heres your refund..lol but they were that useless I binned them anyway..
