Nozzle guard is a must have it's better that it's hard to remove because you don't want it to come off in use.
Works as expected although pricey bought it for the EGO 765 cfm blower. Those are the pros - cons $$ This is a better product than the other stubby add one's that I've seen.

It works nicely. Way better than using the original long tube that comes with the leaf blower. It is a little hard to take off but it's not that bad.

Got this to use with an Ego 650 blower and so far it's not bad. On the plus side it was much easier to use the blower with the stubby. I am short with small hands and the Ego with the regular attachments are obnoxious for me to wield around and this made the blower much easier to maneuver. The downsides for me are the price and removing the stubby from the blower. It was and is a real pain for me to get the stubby off of the blower after use. Again, since my hands are small, I have to use both hands to try to get it off. Hopefully after a few times it will get easier to remove. Overall, I don't regret buying the stubby and would recommend it if you are on the small side and have the $$ to spare.
