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

Not high tech, but if you finish soft metals you'd be surprised at how these finish metals. Better than sandpaper, delicate control

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 wouldn't 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 couldn't find one so this will do.

Makes cleaning items easy

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 don't offer much brushing. I gave it three stars because the metal brushes are more useful but not much.

These work great for cleaning corrosion off of circuit boards and acid from leaky batteries and cracks with debris good quality

Very handy in very small spaces. Just be careful as to how much brush you extend not only to preserve the brush but also to be effective on your work. Nice tool just the same.

I should have known by the low price but this product is junk. 2 of 4 brush handles were fused into the plastic ‘case’ so had to be cut out, and the extra brush heads were so deeply inserted those would have to be cut out as well, essentially making the ‘case’ worthless. The caps that rotate to extend/contract the brush heads pop off when activating and the inside ‘screw’ body pulls right out of the holder. Tried just for kicks to replace a brush head but would t budge to even remove. I’m sending this back thanks to Amazon’s great return policy, and will be looking for a more pro-grade solution.

They do what they should. The adjustment isn't very smooth but hey, it's a much cheaper option and it works.

The product was as I expected

Très efficace pour nettoyer les petites pièces qui étaient rouillées

Je n'avais aucunes attentes envers ce produit, un assemblage plutôt fragile, mais vaut définitivement la peine, nettoie et ravive les petits moteurs a brosses, polis de façon remarquable je n'aurais pu esperer mieux d'un kit a 25$... Oubliez les mauvais commentaires allez y delicatement et vous serez probablement surpris comme je l'ai été!
