Glarks 16Pcs 4 Inch Drill Power Brush Tile Scrubber Scouring Pads Cleaning Kit with 4 Inch Disc Pad Holder for Bathroom & Kitchen Cleaning, 3 Different Stiffness (Red, Gray, Green)

The individual pads don't have an excessively long life but they do a good job of scrubbing everything I tackle with them. Really cleans the soap scum off the glass doors of my shower doesn't scratch it very good functionality they could be a bit more durable but I think if they were they'd be too abrasive. What's the pads are attached they stay attached until you physically remove them.

Lots of options for cleaning anything.

They're not quite as sturdy as I'd like, but for the price they're fine. I use these only occasionally, a few times a year for scrubbing bath and shower stains.

I used it to clean carpet adhesive residue from the bathroom floor. i used it with a right angle drill and it was easy to control. It removed all of the residue. Cleaning materials wouldn't do it, but this did.

decent if all you scrub are smooth bathroom surfaces. But this attaches to a drill, and the drill-attachment doesn't hold up to real scrubbing. I ended up with leftover pads and went to Lowe's to buy a new, more rugged drill attachment to use with this. So it cost me twice.

I've wanted these for awhile and they work great.

I used these to remove dried tile grout. For the price I thought they would break down in no time. Nope, quality product and cheaper than big box stores.

Works great once you get the right end to fit in your drill.
