Doesn't come with instructions or necessary tools.
I gave this four stars because the service kit did not come with the tool to remove the rubber fitting that the propeller attaches to. Also, there are many o-rings that I don't know where they go and there was no lubricant to put on the o-rings. After doing the service on my Fluval FX4 filter, two days later, I had to open the motor housing again because the rubber ends that hold the plastic arm came off and caused the propeller to come loose. I ended up having to superglue the rubber ends on to prevent them from falling off.

Exactly what I needed
Instead of spending hundreds of dollars on a new canister filter I was able to fix the replacement parts. Comes with instructions and is easy to install. Would definitely recommend
