I’ve been buying these when they show up here on Woot for several years. Not too long ago, however, I had to throw two of them away. Once they were opened and I turned the crank at the bottom they started oozing out of the bottom. Not immediately, but within a day one had dripped off of the shelf, under the door of the medicine cabinet and down the wall in my bathroom. It was gross. A second one from the same order did the same thing. This was a while after they could have been returned because I would stock up when they were available and didn’t know they were defective until I tried to use them. Anyway, that pretty much wiped out any savings I thought I’d accrued by buying here instead of Target. 
And now I hesitate to test my luck again…
Oh my, I hope this batch is good.
Finally, a deal that doesn’t stink.
