Okay, so I put this Aidelife dust shroud through absolute hell cutting a massive brick patio (20+ hours of grinding mortar joints!). Here's the real deal:

The good stuff first - this thing fits my DeWalt 4.5" grinder PERFECTLY with the included adapters. Dust collection was shockingly good - only a tiny puff when starting cuts. The transparent window is genius for visibility.

BUT... I saw some reviews about fitment issues and yeah, it's picky. My buddy's cheap Tool Shop grinder needed serious mods (grinding screw heads, notching the shroud) to work. The backing flange is definitely too thin for some grinders - needs like 1/8" more thickness.

Pro tip: If you're doing serious work, maybe get a brand-specific attachment. But for the price? This combo delivers. The diamond blade alone is worth it - crazy durable cutting through brick like butter.

Final verdict? 4/5 stars. Works amazingly when it fits right, but be ready for some McGyver-ing if you've got an off-brand grinder.
