AUPREX Wire Wheel for 4 1/2 Angle Grinder, 4 Inch Knotted Coarse Crimped Wire Wheels, 3 Inch Knotted Coarse Crimped Wire Cup Brush, Angle Grinder Wire Wheel Cup Brush Set with 5/8-11UNC Threaded Arbor

That they were tough and did not break down lasting a long time. Fast service from supplier.

Not as advertised. I got 5 cup wire wheels, no flat wheels and no knotted ones.

This is a pretty comprehensive assortment of wire wheels for your right angle grinder. They seem to be the same quality as the ones youd get at the tool store, and the price is slightly lower. One thing that surprised me a little was that the 4 knotted wheels look flat in the pictures, but they are actually beveled a bit. So, take this into account when ordering, and make sure you have the room to use them. The tool store doesnt carry beveled knotted wheels like this, so as long as you arent working in cramped quarters it might be a feature. The cupped wheels are a little smaller than I am used to, but they still work fine. I did like that these come in a cardboard box as opposed to one of those heavy plastic clamshells that hangs on a display. These are worth checking out as an alternative to the ones from the tool store. For most hobbyists, this will cover just about any task and should last awhile. Recommended.
