I bought this product, few months ago for my 2 and half year old child.
Even if he knows how to blow his nose, the aspirator is still needed, when the nose is stuffed and the nasal secretions are too thick that by blowing are not coming out entirely. In those cases, he alone is using this aspirator.
One bad thing: the hose is too short. I had one before, from Hungary, that had a longer hose, which was better.
I am very surprised to see, that here in UK, there are Not too many options of these nasal aspirator (that may be attached to the hoover). I found it very hard, and only on Amazon, ....and only from two sellers. That's very odd, because, you people, you don't know what you're missing.
You don't know how useful this is, and how much trouble free becomes those times when our child has got the flue.
It is not dangerous at all !!! Easy to clean, by the tap with the hot water flow. When the nose is too stuffed, we used to turn the hoover at maximum power 1800 W, and there is NO problem at all with the child's nose. Just a bit noisy, but that is not a problem, on my opinion.
You don't buy one? Your loss.
I recommend it.
