2 Pack AF-100 Polycarbonate Replacement Head Blades Compatible with Black Decker GH912 GH900 GH600 GH400 GH500 String Trimmers,with 12 Pack Flexible Replacement Blades, Screw Parts (21 Pack)

Is for a black and Decker weed whacker. Fits spools and works very well.

Easy to assemble, works like a charm. I even wacked some harder objects a few times by accident and there was no chipping or cracking of the blades.

Work perfect with my Black & Decker automatic feed. Will be stocking up on these.

Exactly as seen in the web site. This is what I needed.

Exactly what I needed. Great price compared to the home centers

YOU - are smarter than I was when I bought this! YOU are reading the reviews. I DIDN'T. I am SO tired of string trimmer line! So tired that I bought what sounded like a really good idea. The Seller shipped VERY quickly. No issues. The product is exactly what was listed, and the design is really innovative! . The problem? Read the listing - the "blades" are Polycarbonate - that sounds "TUFF". It turns out that Polycarbonate is a big word that means "fragile plastic". I had about 180 feet to weed-whack, a lot of it bordered by 2x6 pressure treated wood. I tried the blades, they broke within 50', so I tried the "dual whips" they lasted better but still gave up the ghost. by the time I finished the 180', I destroyed 2-pair of blades & 1-1/2 sets of whips. (The whips last better.) I should have given thought as to why the kit came with so many sets of cutters. The Upside? It's REALLY easy to change the cutters! The installed kit is really light, but the "torsional pull" is a lot harder with either cutter set than using .065 trimmer line. Over all, I think I'll go back to trimmer line when I bust the rest of the cutters. Whether you waste your money, or not, is up to you.

Segunda vez que los compró, funciona muy bien en mi podadora Black+Decker, traen 6 y por este costo compraría solo una en un almacén local

Great price!!!
