Ex Input:
Reformulated in Jan 2018 - horrible. Super runny, no lather. Seems like a ploy to get you to use 2-3x as much product each wash as it just flops everywhere when you try and squeeze a little amount out. My breakouts are back to what there were before. The old formula had pretty much cleared me up. One week with this new one and I’m back to being self-conscious again. I’m going to scour local drugstores for the old version and if I can’t find it, switch brands.

Ex Output:
negative


Ex Input:
I thought the impeller was broken so I purchased a new one and unfortunately learned that it is the filter itself that is no longer able to pump water. I bought this a month ago. My turtles are not happy.

Ex Output:
negative


Ex Input:
Terrible, but I should have known since it was so inexpensive. Came vacuum packed, and was completely misshapen when unpackaged. Also, the advertisement said that it was a two-pack, only one pillow came.

Ex Output:

negative
