Rated 4.0 out of 5.0 by Tom3 Looks well made
I got this on the off chance it might fit my non Makita angle grinder but unfortunately it doesn't. The dust shroud however appears very well made and easy to install.
The top that mounts to your grinder has springs and floats which allows you to push the blade down to accommodate different blade thicknesses.
It's hard to tell from the photo listed but a portion of the dust collector comes off to allow you to grind close to edges. It simply slides on and off without tools.

Rated 4.0 out of 5.0 by fxp1 Keeps down dust when grinding concrete and paint floors
The Makita 4-1/2 in. Dust Collecting Wheel Guard is a shroud covering to contain primarily concrete and paint dust from floor grinding which can be a problem. It gets everywhere and is unhealthy to inhale besides. The wheel guard is tough plastic which I'd say is made of ABS plastic. It has a metal spring and plate mechanism to hold the guard down to the floor. The spring could have been longer to allow for more travel with different wheels. The cover uses a cup wheel and some are deeper than others. Its compact and smaller than I expected and others I've seen. A section of the front plastic cover can be removed to get up close to walls with the wheel. The cover has an interesting locking mechanism with a sliding lock. Around the perimeter of the guard is a small brush strip to keep the dust in the guard and out the vacuum exhaust port. The exhaust port is small and fits loosely my 1 1/4” vacuum fitting. The guard does a good job corralling dust if kept up against the floor. The dust is very fine so watch it doesn't burn out your shop vac motor, clean the filter often and duct tape the port if needed. It does a fine job for its special use of trapping dust.

Rated 4.0 out of 5.0 by BEAU4U OOP'S... Not What I Thought
I needed to cut some drainage grooves in concrete. I have a Makita 9557NB 41/2" grinder with several types of wheels. I have been putting this off knowing that it will create so much dust that it could cause a Nuclear Winter. When I saw this item I thought perfect, I have the grinder and lot's of grinding wheels.
Well not so fast , in reading the manual , the first thing that caught my eye was you need to use a Diamond "cup" wheel and the collector is only designed to use parallel to the working surface. No. 1
the blade is anywhere from 35-55 dollars. No. 2 I think the description should have been a little clearer and at least used the word "horizontal" dust collecting wheel. You have to use a 'cup" wheel because a flat wheel would scrape on the collector, some call this a "depressed" center, but technically "cup" versus "depressed" is different . So just to see if it would work I took a depressed center wheel and a combination of flat and lock washers to build up the wheel just enough so it would not hit the collector. Found a broken concrete block that still had enough of a flat surface for testing. Hooked up the grinder and my shop vac and ...... yes as long as you keep the dust cover horizontal you will contain the dust enough for the shop vac to catch it. I didn't do this to long just enough to see if it worked, why waste a good wheel, I gave the ratings I did because the tool does what it was designed to do and the fact that it doesn't do what I thought it would do is not the tools fault.
