Product review (1 stars): Read the bad reviews, over 25% are bad for a reason.
Despite a significant number of poor reviews, I bought this product.  I saw the Boneco company feedback that one needs to follow the instructions carefully.  I did.  To the letter.  Yet, no amount of instructions can turn a bad product into a good one.  The granules are so tiny that water can barely pass through them.  Therefore my humidifier cannot keep water in it.  It dispenses the water before it can refill.  This was never a problem before.  My 200+ dollar humidifier is useless.  Next time, I will just buy the $20 Sunbeam.  It works forever and no problems.
