I love Kobalt battery-powered tools. I've owned the Kobalt 40V string trimmer for several years and have been very happy with it, so adding this blower was an easy decision. No more mixing fuel, pulling starter cords, or dealing with engine maintenance. The blower has plenty of power for clearing grass clippings, leaves, and debris from my driveway, sidewalks, and yard. The battery life has been more than adequate for my needs, and it's lightweight and easy to handle. If you're already invest...

Wow- it really means business
This is a strong blower- very close to the corded model I’m replacing, and a lot quieter- it picks up leaves immediately and will easily blow the trimmer mess on my driveway all the way across the street if I’m not careful…and quickly. It’s pretty surprising for a battery operated unit. There is a cost- it eats battery quickly. However, since I bought a mower and trimmer as well, and the mower and trimmer use battery much more modestly, I have the other two batteries to supplement if I run l...

Easy to handle leaf blower that fits typical needs
The blower is lightweight with an easy trigger and "cruise control" setting. The battery lasts a decent while and charges quickly. Overall, a solid entry/mid range leaf blower for most general yard use.

90 minute run time SCAM
I bought a craftsman blower from Lowes and ran 3 tanks of gas through it without a hiccup. Day two, ran it for 10 min, turned it off, 10 min later I pulled both arms out of joint and it never sputtered. Returned it to Lowes and got a refund. Decided to try battery operated. Bought the Kobalt. Read the box. Cool, two batteries. I can run it with one while the other battery is charging. Nope, it takes both batteries but only comes with one charger. Out of the box, it ran for 30 seconds and died. P...
doesn't last long enough
I rarely use this but a few short times a year to blow off my patio. the battery quit at 2 years and I never overcharged it. it does have good power though

Great features
I really like the extended run time battery included with the leaf blower. It provides enough power to get the job completed. The blower is easy to manage and can be disassembled for storage.

Kobalt leaf blower
Great power and long lasting battery. I am 76 yrs. old and I can operate this leaf blower with no problems. It is not too heavy and very powerful. I would recommend this leaf blower to anyone needing a battery powerd blower.

Powerful easy to use blower
Works well and can set cruise control to not have to hold button. Wish it came with attachment to concentrate air in smaller space

Great little tree
Bought this 40-volt on sale because it was cheaper than buying another battery for my older model, it gets the job done but seems to lack a little less power than my older model, but the bright side of course is that the batteries are interchangeable.

Great for the price!
The power and the adjustable output was great. I love how it has a turbo mode and a switch to put it on cruise control
