Glue was totally dried up
I got this product (not from Amazon) to have on hand for my next broken nail emergency.  I opened it about a month after getting it and the glue was totally and completely dry!  The place I bought it at says that is a common complaint.  I didn't have the receipt and had to buy a replacement glue on my own dime.  The powder in the kit did do the trick for me though.
