The yard sales are starting to pop up , and that is something that I always look forward to each year. We went to one just down the road from us today, and they had a combination set that included a battery operated string trimmer and also a leaf blower. They each came with a 20 volt battery and a charging bracket , and the batteries are interchangible for each one. We have other weedeaters, but my favorite one has turned out to be my Black and Decker one that is also battery operated. It is much easier to start and operate than my gas powered one, but I don't have to have a power cord like I do with the little electric ones. So, when I saw this one at the yard sale, I was elated ! If I have two of these, one can always be charging while I am using the other one, plus this new one came with two batteries, since one is for the leaf blower, so I should always have at least one of them charged up and ready to use. They were asking $30; but I offered them $20, and they accepted that. When I got home, I looked it up online, and the set sells new for $180; so now I am really pleased ! ! We have the battery packs charging, and they will be ready to go by tomorrow if the weather is nice. The leaf blower is perfect for cleaning off the porch and sidewalk, and then I can take the trimmer to the weeds growing up around the sidewalk.
