    Good product

    Right up front I have to stress: Don't confuse a "corded" product with a "cordless". This is a corded machine, meaning it is constantly connected to an electrical source...and this gives it SO much more power. I have 1.5 acres of lawn to weedwhack after mowing (lots of trees) and this B&D gets the job done. It's lightweight, auto feed and doesn't vibrate as much as others I've tried in the past. Plus, I purchased it after Walmart started it's end-of-summer sales.

    I purchased the Black & Decker 13'' Automatic Feed Trimmer/Edger Model ST7700 because I needed a weedeater that was lightweight and easy to use. This was easy to assemble, (very minimal) and easy to use. Just plug it in and go.

    This is the 2nd season that I've had the trimmer and it works great for me. I only do the edges of the driveway and around the house, so it's not used heavily. It's light & I don't have to yank on any cords to start it so I can use it myself. I love it.

    • It would seem so, but I have done a large area twice, through thick and thin, tall and short, and I still seem to have a lot of string left. By the way, the string doesn't get tangled and releases smoothly with no trouble.

    • Yes. The Black and Decker AF-100 spool. It is carried by Walmart. A pack of two spools costs about $10.

    • It uses .065 in. round nylon line. You can buy replacement line and rewind the spool or buy prewound spools.

    • You can buy the replacement spools online (2 for $9.99) or in the store(not sure of cost) or if you like you can buy line in bulk and wind it yourself. Personal choice berween convience and cost. I buy the replacements because its faster and easier.

    • use string recommended on the box or owners manual. Do not restring spool because you will never get it factory tight and this will cause problems!

    • No. The line size is listed on the side of the box and I got mine at the local hardware store.

    • Yes, I assume it does, since it will automatically remove the frayed end, making the string shorter. The more things you hit with it, like trees, bldgs, etc. The faster you'll go through the line
