Example Input: Like other reviewers, I'm disappointed they changed the formula. My dog has a bunch of problems and pees/poo's himself everytime he goes out. I use these in-between baths to keep him clean and they used to be a LIFESAVER. With the new formula he doesn't get nearly as clean as he used to and he still smells. They work and I be see soils coming off, just not completely.
Example Output: 3

Example Input: Shorter than expected. Kind of difficult to put on and lace up. The jewels were coming off, upside down and neither of the gloves looked like the other. I will need to spend some time fixing and sprucing these up.
Example Output: 3

Example Input: I receive the powerstrip and when moving it around I heard something rattling around inside. Upon opening it I found one of the clips for the brackets holding the power wires in place floating around inside. I do not trust this product to hold the live AC wires in place and not short each other.
Example Output:
