YETTAT Flat Tip Nozzle for Kobalt 24v Leaf Blower Flare Tip Nozzle fits KHB 4124B-03 24 Volt

I purchased this optional nozzle for my Kobalt leaf blower 40V Max 4.0 AH. The product fits perfectly on the blower definitely a great product at a great value checked other sources which were much more money. Very happy with this product would recommended to all others.

This doesn’t fit on my blower as there are two clips at the end of my blower. Tried heating the tip up and trying to fit it on, but that didn’t work. Finally I just shoved it on and much as I could. When tired to use it, the tip restricted the air and sent back pressure to the motor. 5 seconds later, the tip blew off. I’m returning it.

Works better than expected, nice secure fit on the blower, directs the air exactly where you want it to go.

You MUST install it with the orientation VERTICALLY to get the most benefit. I know that sounds counter-intuitive, but it's true. I first installed it on the end of the blower with the orientation parallel to the ground and it was *maybe* marginally better. Then on a whim I decided to try it vertically. OMG it was so much better. It allowed me to reduce the speed of the blower and I was able to get half my yard done on 3/4 of one battery. Without the concentrator the entire yard took more than 4 battery charges because the blower is wildly inefficient. The key is that you don't need full power with the concentrator on vertically.

Does NOT fit or stay on.
