Yes, I would recommend this.

Good budget protein skimmer

Pros: Price, easy install, good build quality

Cons: Can produce micro bubbles due to the smallest input changes, finicky

For the price point, it is a decent skimmer. It did not take much breaking in to start pulling a decent amount of skimmate. It can be a little finicky when setting up. It's performance is susceptible to the smallest water height and air intake changes. It can also spontaneously produce a lot of micro bubbles because of these changes. Overall, it is a good skimmer for it's price point.
