Poor Quality
I have been buying these drops for years.  I started with this brand but noticed that the price had risen so I purchased a cheaper brand which was good.  I noticed the Pure brand was a bit cheaper this time so I bought them.  Devil in the details!  The bottle is half the size now and the solution has been diluted.  I tried to return but this product is "unreturnable" despite not being opened and sealed.  Such a shame.
