8 Pieces Scratch Brush Pen Set, Pen Style Prep Sanding Brush With Steel, Brass, Fiberglass, Nylon Replacement Tips for Jewelry, Watch, Coin Cleaning, Electronic Applications, Auto Body Work

Very nice set of scratch brushes. Very compact and work well.

Fantastic idea I havent used yet seem to be a little flimsy might break easily I purchased to clean corrosion out of AAA battery compartments on camera equipment. I love the way you can extend and retract the brush Not sure how the plastic will hold up with electronics cleaner spray might melt or the metal tip hold up with simple green or other water based cleaner might rust

I have used a these a few times and they done the job I expected of them. They definitely helped reaching areas that I could reach with my fingers.

The fiberglass brush worked as expected but the nylon brush was a happy surprise with how well it performed!

It is surprisingly difficult to find fiberglass scratch brushes for electronics. I have been using this for a week or so and the fiberglass cleans traces well and I find myself using the nylon and brass more than I expected. The nylon is good for cleaning solder joints where you need something firmer to get old flux off or baked on crud. This set came with replacement brushes, I have no idea if the bodies will last that long. As mentioned in other reviews the bodies are a little on the cheap side. For the price it wouldnt be painful if I had to buy a new set every year. It would be nice if someone would make a really nice sturdy set, something you would keep for a lifetime. One of my friends who does electronic repair has a 3/4 fiberglass scratch brush and he said it was really expensive. I couldnt find one so this will do.

Works as described no issues

very cheaply made

No instructions. Tips seem hard to change, and unsure as no instructions.

Product does come with two metal plus one plastic bristle brush pens and replacements. The product is cheaply made so taking the existing brush to put a replacement literally destroys the pen itself so it is pretty much impossible to use that replacement with the existing pen. The brushes are also very weak and flimsy so they dont offer much brushing. I gave it three stars because the metal brushes are more useful but not much.

This product was not capable of doing gradual whiteout or whiteout period and that is what it needs to do
