I have seen 'QH' written after the dose names, something like:

AcidQH

So, what does this QH stand for and what is its meaning??


Thanks

hmm.... those are earphones.

I guess, a closer ear 'headphones' should be better.

How safe is this I-doser for children about 15-17 year old?
Since 15-17 year old are students, so will it be safe for them to use I-doser?

Can this be guaranteed that I-doser will not 'harm' their mind and which can harm their studies?


Thanks
