I give it a star for price as I purchased on sale at a local Woodcraft store for $16. However, I will be returning it. Woodcraft's website says this fits 2-1/2" shop vac hoses. Wrong. A standard 2-1/2" vacuum hose is too small to fit over the connector and too large to fit inside it. In fact, they are similar diameters. ONly the fact that the cyclone's connectors are a thicker plastic than the vacuum hose, make them somewhat different diameters both inside and out. I do not want to take time to force fit or search out adapters to make the connections work. It is also true the lid fits loosely on 5-gallon buckets and you would also need to rig a way to strengthen the fit so dust did not escape and so the lid did not fall off when hoses are moved or the bucket bumped. A total dud in my opinion.
