Review on 300-Pack Steel Wire Brush Set With Rotary Tool Accessories - Rocaris Wire Wheels, Pen Brushes Kit For Improved Cleaning And Polishing by John Maskirta

I gave 4 stars because:1) order arrived on promised day about noon. This was good because I got the rest of the day's use of product.2) opened box & counted-received exact qty ordered.3) giving benefit of doubt on quality till I use some.I examined the "T" shaped brushes. Their assembly is inconsistent. On about 10 of 20 it looks like the pieces were poorly aligned before compression & the parts that hold the wires are not parallel. I believe those will come apart most easily.I intend to update review after using some.UPDATE-for my current project, I used primarily the "T" brushes (round & flat, attached to the end of the mandrel). My earlier assessment was accurate-those with poorly-aligned parts spun apart in a shorter time. In all fairness, name-brand brushes lasted only a little longer than those assembled accurately. That makes the value for the money pretty good. After all, these brushes are consumable, like sandpaper.The mix of 3 types was not good for my needs this time. Maybe I'll need the other types later, but I'd have preferred all 1 type.In the end, I'll give 3-1/2 stars which rounds up to 4.OH.YOU MUST MUST MUST WEAR EYE PROTECTION USING THIS PRODUCT UNLESS YOU WANT AN EYE INJURY. I recommend a face shield & long sleeves (2 layers better) unless you enjoy tiny wires sticking in you.
