This is exactly the type I use. You fill it up with TEPID water (feels neither warm or cold). You insert the tip in your ear canal a comfortable distance (1/2")and BLAST the water in there. It is the flow that matters. The temperature is so you maintain your equilibrium. Keep your head level. It may take 6-7 bulbs full.
You should feel a tingling almost ticklish sensation as the stream rushes down your ear canal. Even at max discharge the water pressure will not damage your eardrum. You need the pressure to dislodge the wax. I often get solid pieces out about the size of an eraser on a new #2 pencil.
If you experience pain you could have an infection or other problem so cease with the irrigation and see a doctor.
My hearing improves instantly. You are likely to feel slightly dizzy for moment and have some water drainage for a minute but it is very effective and much better and safer than Q tips.
This whole thing is convincing me even more that my Q tip every day after showering routine is the right way to go.
I'm not talking about using them after letting it build up to this point, but keeping it from building up in the first place.
My doctor told me it's actually not good for your ears to 'clean' them frequently, that wax build up is a defense, it also keeps a level of moisture in your ear to prevent painful dry skin.
I was told to q-tip only when it was excessive and wasn't naturally draining (ear wax will periodically fall out of your ears, sort of like boogers.)
Edit: Why don't you work quotes? Too good for me?
