This two pack of handy garden tools consists of a Leaf blower and a Hedge trimmer that will accommodate DeWalt 20V Max style batteries! An excellent bargain in a two pack of tools that most people will use to clean off their patio after trimming their garden bushes, for example. Tried and tested, they both work fantastic! They look great even though these are not actual DeWalt Tools they do have the same color scheme as the DeWalt tool line, matching them perfectly. The Hedge trimmer comes with a nice safety storage sleeve for the dual sided cutting blade. Also for safety, I like how the Hedge trimmer D-Handle requires a grip along with the trigger to operate it. There is an inner safety bar that wraps around the inner side of the D-Handle for optimum gripping and safe usability, it does not limit or inhibit the operation. The Blower has a 5 speed thumb wheel control (1-5) and is located at the top forward section of the grip handle, very easy to reach and to control. Great Quality and both together are an Excellent Value, very nice!

Not bad for the price, trust the hardware not the brand

Used it one time, but will leave a review for those wondering. Trimmer: Worked well for out of control vines and leafy hedge. It had enough power and was sharp enough to do the job I wanted which I'd say was small to medium size. I am sure overtime it'll dull, but for the initial tryout I'd give it a 9/10. Feels great in hand, light weight, has the ability to switch from top to side cutting. Blower: Pretty good power, but chews through battery. Absolutely does the job and is very lightweight and easy to use. 10/10 Overall, for the package price I'd say it's worth it. Who knows how long these cheap devices will last, but for light to moderate yard and lawn care they should do the job. If you live on some farm in Iowa then you'll probably want something better and stronger. But for those with a small backyard in the subs somewhere it's more than capable. Batteries are not included. I had used and picked up the aftermarket 8MAH max (DeWalt clones) 2-pack for $50.
