Macro Aqua M-50 Skimmer?

[WhiskeyCoffee]

Someone nearby is selling an entire tank and one of the pieces that comes with it is a Macro Aqua M-50 HOB skimmer. When I went to go look at it, it was full of skimmate so I guess that proves it works? idk. Here's an Amazon link.

Price isn't a huge concern for me because as I said it comes with a tank. I don't have a skimmer right now but I'm looking to add one to my sump. What do you guys think of this model?
