Poor quality but great convenience the extractor. It is sharp to make a hole but it does not convince. Its construction should have been a little more sturdy because it looks fake and if you force it, it will break. Not to mention that its blade bends with the slightest impact. I bought it solely for the extractor because regular pliers will drive you crazy if the small piece from the rubber you are cutting gets stuck inside. Their price is quite expensive for their quality. Maybe if I find a solution for cleaning the regular pliers, I will not use this one again.
