The build quality and grip is solid. I purchased it as I was tired of ratcheting bolts off our oven I was fixing. It definitely was not necessary but had an immediate improvement on quality of life. If you deal with these size bolt heads often I would definitely pick this up.

Muy buen desarmador en la línea de Klein tools excelente no me arrepiento de haberlo comprado es una buena compra y por el precio está genial más aparte aquí en México pues está difícil conseguirlo en una ferretería sería mejor comprarlo por Amazon en línea
