    Have been waiting to acquire since advertised last summer for spring debut. Wanted something for cleanup around swimming pool, tired of fighting a gas powered vacuum!!! I had planted "cat-claw" around my entire back yard to completely hide block walls [they drop dead leaves daily], have many deciduous trees, both neighbors have large mature pine trees [the winds here clean out the abundant dead pine needles & immature pods], and easily vacuums live pine shoots when I trim cedar bushes. I can remove all debris around me entire back yard in the time it took me to start my gas vacuum and keep it operating. Highly recommend.

    Works as advertised.
    Have used the product to maintain about 1.5 acres. Used some 35 times so far with no issues. This is better than claimed; however, it WILL NOT mulch wet leaves and branches (not supposed to). Although not advertised to do so, it will blow dry leaves from flower beds and such (other than hard surface). The battery life is better than I expected. Average time of use is 30 - 45 minutes on high setting. If there is a downside, it's the vac nozzle cannot be turned 180 degrees (so miter is up rather than down). Makes setup and assembly easier, just wanted to try the configuration. The tubes go together hard; however, they stay together. Situation is well covered in instructions.

    Light weight, quick & easy
    I have a cellar stair well that fills with leaves causing the basement to flood. Bought this unit to keep adjacent to the basement door to vacuum leaves prior to rain storms. Perfect for this application. Picks up a full bag of leaves on full power without any noticeable loss of battery power. Bag is simple to remove and dump.

    Great all around cleanup tool
    I do a lot of yardwork as well as build furniture in my small shop. I had several electric leaf blowers that usually were very noisy and in my shop the cord was frequently getting tangled around pieces of equipment, then more often than not the cord would end up in knots. Most my woodworking power tools have dust extraction, but for fine detail work there was the issue of fine dust that was not only difficult to work around but hazardous as well. This blower is great for quick cleanup and best of all it's fairly quiet, it's also very handy to clean up the patio area after my wife has worked on her flower pots. With two other 40 volt Black & Decker yard units and their respective batteries/chargers I could easily run this all day and never run out of power. I wouldn't recommend this for vacuuming or anything wet or heavy, I'll retain my bigger leaf blower for jobs like this.

    Helps me out a lot
    Leaves in the Fall have always been a bit of a problem for me. I have a sunken driveway which collects leaves and a fence in the backyard that leaves blow up against. This Black & Decker works really well at blowing leaves where I can get to them to collect/mulch them up.
    The battery holds up fairly well (I have a trimmer that uses the same 36 v batteries) and I always let it "rest" a while before re-charging so it's good to have an extra around.
    I'd buy this unit again in a second if anything ever happened to the one I have. It's easy to convert back and forth, lightweight, and has plenty of vacuum.

    Does very well
    This was exactly what we were looking for. It does a very good job on blowing leaves and like lasts a good while if the battery has a full charge. Has more power than expected. I the fact that there is no gas to mess with or cords to drag around. It was ready to charge and use right out of the box. I already had a 36 volt weed eater and the 40 volt does seem to be better but the batteries are interchangeable. Overall happy with the purchase. The price and shipping was fast and reasonable.

    how does it handle pine needles and/or wet leaves?

    BEST ANSWER: For wet leaves you need to go slow so that they don't jam up in the chute. The big thing is to allow for plenty or air circulation along with what is being picked up.
