I purchased these little treats as stocking stuffers for our little furry friends.  Both Yorkies LOVED these treats.  We had to finally buy more since they liked them so much.

I was on subscribe and save for these mints, but have switched to Spry due to Xylitol USA's awful company policy and customer service. If you buy something from Xylitol USA that arrives in bad shape and you want to return it for a refund, the company will tell you that they do not accept food back. When I insisted that the product was old (in my case two bags of xylitol sweetened dark chocolates that were old, whitish and tasteless) they said that they would NOT refund my money and, amazingly enough, offered a 25% discount on my NEXT purchase. I disputed the payment and my bank took care of the situation got me my  money back. No more purchases from this company for me.

With no clear instructions on how to open and close the unit, the first few times are an act of frustration.  When I finally realized that if I grip with my thumb and forefinger over the clear plastic shield, about one third from it's bottom and squeeze the sides, the bottom lip pops out nicely. I will agree that this size is too small for most popular herbs like parsley, basil ect.  The company does now make a larger unit and it looks like it is more user friendly. All in all I like it, I took away one star for the lack of instructions.  3/2012: After a few months I have thrown this thing away.  It became increasingly harder to open and the size was just too small for the herbs I use most.  I have seen some newer, larger units that don't have the issue with opening it like this one has...I'm going to order one of these.  I no longer recommend this unit and have lowered it to 2 stars.
