Rated 5 out of 5 by from Great Value I bought this in a 3 pack with blower ad mower. Its perfect for my size (somewhat smaller) lot. It does more then enough for me and is a great value and wont have to buy gas or deal with the vibrations and noise!

Rated 5 out of 5 by from Amazing Trimmer! Just bought this from the Ryobi days deal. 2,4,6, ah batteries and a weed Wacker for $200! Can't beat it! I am super impressed! This thing has so much power! Even on the low speed setting, the thing slices through weeds no problem! On high, I think it may be able to break skin. I accidentally got a bit too close to my downspouts and the weed Wacker tore through the bottom of it and flung little bits of aluminum across my yard! Definitely be careful how close you get to things you don't want cut! This thing can do some serious damage! And the battery life is great! I was upgrading from a 10+ year old black and decker weed Wacker and this thing puts it to shame! It's so much better than even when the black and decker was brand new! Battery tech has come a long way! I love my Ryobi yard tools! Some very nice features on the weed Wacker...the lock/trigger on top/bottom are positioned nicely. The weed Wacker has nice balance and as a 6'4 tall man I like the long shaft. No need to bend down to weed wack! As I mentioned the high/low speeds both work very well and give plenty of power! The push button to spin the handle for edging is very nice, and the autofeed line is great! No more bumping! Finally I'll get to my only real complaint with the weed Wacker. The string that was attached to the weed Wacker from the factory bogged down on me and wouldn't auto advance. I took apart the spool and found that it was bound up on itself and unable to feed out. I unwound and rewound the line and didn't have any more issues, so doesn't seem like a big deal. Perhaps an issue from the weed Wacker sitting on a shelf for who knows how long...anyways, that shouldn't really be an issue long term and seems like more of a one off. If that's the only problem with this machine, that's fantastic! I'd definitely recommend this weed wacker! Buy it! You won't be disappointed!

Rated 5 out of 5 by from Awesome tool! Bought this a month ago and haven't needed to charge it. I have a small yard that needed some edging done, this got the work done quickly and smoothly. I also found that the stock string is stronger than other brands so I haven't felt the need to swap that out.

Rated 4 out of 5 by from Great for home use Easy to use all around, whether changing heads or switching from trimmer to edger.
