Just got my hands on the HERZO dust shroud for my angle grinder, and here's the real talk after testing it out.

First off, the universal compatibility claim? Mostly true! It fits my Bosch 1803EVS, but man, it was a TIGHT squeeze. Had to wrestle with it a bit - feels like the metal collar could use some sanding down. Pro tip: keep your grinder's specs handy before buying.

The dust control is LEGIT. Did some concrete grinding (finally tackled that patio project), and wow - about 90% less dust flying around. My lungs and white t-shirt thank you, HERZO. The spring-loaded brush is genius - contours to uneven surfaces like magic.

Transparent design = game changer. No more guessing where I'm grinding! The flip-up corner feature saved me when working near walls. Though heads up - that plastic crossbar can limit tilt angles sometimes.

Installation took some finessing (those spacer rings confused me at first), but once mounted? Solid as a rock. That said, this ain't a quick-swap accessory - save it for big jobs where dust control matters.

Major bonus: Comes with EVERYTHING - even a super handy angled wrench that's better than my grinder's original! Though fair warning: might not fit all vacuum hoses perfectly (my shop vac needed an adapter).

Downsides? Not great for metalwork (sparks would melt this baby), and wheel selection gets limited. Also had one grinder it just wouldn't play nice with despite the 'universal' claim.

Final verdict? At $30, it's worth every penny IF your setup matches well. Not perfect, but when it works? Total workshop upgrade!
