Let's talk about the HERZO Dust Shroud for angle grinders. First off, the universal compatibility claim? Mostly true. It fits most 4-1/2'' and 5'' grinders, but be warned - some models (looking at you, Bosch) require serious elbow grease to install. That thick metal collar doesn't play nice with tight spaces.

The dust control is where this baby shines. We're talking 90% less dust in your face and workspace. The spring-loaded brush is genius - it contours to uneven surfaces like a champ. But here's the kicker: that clear polycarbonate body gives you perfect visibility while grinding. No more guessing games!

Now for the not-so-great parts. The installation can be finicky, and some users report fit issues with certain grinders. Also, while it's perfect for concrete and wood, metal grinding? Forget about it - those sparks will melt this plastic faster than ice cream in July.

The included accessories are a nice touch - especially that angled spanner wrench (saves so much frustration!). But that mystery washer in the kit? Still trying to figure that one out...

Bottom line: If you do lots of dust-producing grinding, this is worth every penny. Just make sure your grinder plays nice with it first. For quick jobs? Probably not worth the setup time.
