I've had wax and wax compaction problems since I was young.
Regular use of a few drops of warm Olive Oil BPC keeps most ear wax problems away. Get a bottle dropper from the chemist (under £3 for both from a chemist).
Of course you sometimes forget your oil regime or sometimes an excess of dead skin comes away in the ear and you get a wax/skin ball that work it's way into every silly nook of the ear.
I did. Olive oil might get it out but you often just finish with a clean/sticky wax/skin ball. My ear had remained blocked to sound for 10 days, despite a warm olive oil lake flowing through every few hours - no sign of anything leaving but it felt loose.
I was told I can get an appointment with a nurse in about a week...
The Acu Life aims its three jets (at 120 degress to each other) sideways - imagine how an inverted tripod looks - so there's no risk of a direct down the ear canal hit on the ear drum. Which is what I wanted to avoid if I was tackling it myself.
So I ordered one and the day after, and one cup of warm water later its all clear. The 20ml size is a good size for each squirt (gently until you get used to it), mine cleared after about 6 squirts. It's a bit messy when the water runs back out, down your chin, misses the basin to catch it - so find a sink and keep a towel handy.
The simple ideas are often the best. Wax removal made easy.
And of course - Read the instructions! I had no pain, it felt very pleasant. My other ear wants a go!
