Customer Reviews

Get these extra spools and buy bulk line.
I somewhat agree with the guy from Vegas that this is a waste of money, EXCEPT that this is about the only way to get extra spools for your Black & Decker weed whacker. Note that you can buy a spool of 600 feet of .065 line from Amazon (Desert Extrusion brand, price is $8.80 for 600 feet in March 2007). Then, with the bulk line, plus these 3 spools, plus the spool that came with the weed whacker you can have up to 4 spools ready to rock and roll at minimal cost. Unlike the guy from Vegas, it takes me more than 2 minutes to hand-wind a spool, but not a lot longer, it's pretty easy to do, my main advice being I find it better to not try and wind more than 25 feet onto a spool even though it presumably can hold 30 feet of line. Everytime I wind more than 25 feet I get a lot of jams until the line gets those extra few feet chewed off. Hope this helps.

Don't waste your money
What the other reviewers fail to mention, maybe because they failed to try, is that the AFS on the trimmer continues to work flawlessly with hand wound string, and at less than 1/4 the cost it's seems like a huge waste to buy the pre-wound spools. It only takes 2 minutes to rewind a spool, so even when I do run out in the middle of a job, I just look at it as a 2-minute break from yard work. Of course, if your one and only concern is convenience, you may be looking at the right product. Be aware, if you've had trouble with rewinding trimmers in the past, it may be because you're using old line, which tends to get brittle over time. Buy some new line and try again. If you buy the three-pack of spools three times, you just paid for your trimmer again.
Thanks for reading,
Adam
ps. Two stars for effort, but the cost is just ridiculous.

AF-100 on GH400 Trimmer Edger
The factory replacement spool for the GH400 Trimmer/Edger is the way to go. I have been very pleased with the easy to load and use spools. I have had bad luck with other trimmers, but this one is great with the factory replacement spool.
