Nozzle on refill too easily broken...
I *just* purchased this product, I went to remove the cap from the refill (since my store didn't carry a starter pack, only the spray unit and refills). The cap was on the can so tight that when I finally did manage to get it off, it snapped the nozzle right off.
And from what I've found by doing a simple google search... I am not the only one that has this problem. Which leads me to believe it's just an overall poor design.
I have to now run out and buy another refill, if the same thing happens, I'm just throwing the entire thing in the trash.
