Review: Los prolongadores están bien por el precio que tienen , de hecho tienen un moleteado que es de agradecer. Otra cosa es extraer los prolongadores de los machos de plástico donde vienen encastrados , tardé casi una hora en extraerlos con un destornillador y un martillo para ir vaciando de plástico las hembras de los prolongadores, de hecho, el ultimo he tenido que esperar a tener disponible un tornillo de banco para poder sujetarlo y acabar de arrancar el plástico con un destornillador y un martillo. No hice mucho caso a los comentarios en Ingles pero todos tenían razon.
Review: It's disappointing how much blame this excellent quality and best priced extension set got because of the packaging. I must say it almost deterred me from buying as well, but then I thought.... surely I can remove a bit of plastic out of a metal hole and pay at least $10 less for exactly same thing. So I got the set. Same decent quality as of other Powerbuilt tools. The packaging... I was holding the plastic holder with my one hand and just wiggled the extension bits one by one with my other hand. No tools used.
