Review on Enhanced Dust Collector/Vacuum Fittings - POWERTEC 70133 2-1/2-Inch Blast Gate by Evan Hernandez

Describing this product as "self-cleaning" is ridiculous. If you buy this, expect to frequently have to disassemble your system to take it out and clean it. Oh, and by cleaning I mean you CANNOT clean them effectively. The chute, where material accumulates and makes you unable to close it properly, is so deep you can't even get a tool to clean it! Everything about it is disappointing and not worth it. It's time to swap them out for something better. I wish I had never spent money on them.
