Great deal!!! Get this combo now. The Dewalt batteries clip in securely. The trimmer is light and did 12 large bushes and still had 2 bars on the battery. The blower is handy for quick patio blow offs, garage blow outs etc as compared to strapping on the big backpack blower. Both were beyond what I expected.

Don't Expect It Last

Size: 8.7-INCH

Hedger works as described, BUT the drive hub on the blade came/broke off. So its no good and worthless. Worked about 4 months...I did work it hard though. New blade is only nine bucks so I'll buy a new blade...I would have expected it to last a little longer.

Size: Single of 13 fl. oz, Number of Items: 1

This is a very good 50:1 oil mix for my weed eater and the chain saw, Large enough for the price and easy to mix 50:1 for both weed eater and the chainsaw . Right on time as i did use some old mix then had to clean out the fuel tank, This new mix took care of that well, not as much smoke either now, Performance is good and does not smelll bad like the old mix was. thanks !
