I'm really happy with the power and battery life of this machine. The nozzle is narrower than the one on the E-go machine, so it fits inside most roof gutters.
It has three speed settings, plus and on and off switch. Along with the three speed settings, the throttle can be gripped harder or softer to change speed.
When I use the machine for cleanup of hard surfaces on the ground, it's usually in the first or second setting. When I'm trying to blast wet crap out of roof gutters, . I use it on the third, maximum setting.
Today I put a handy extension on the nozzle, so that I could reach nine feet from the hand position. This allowed me to clean a very difficult area between a deck and a lower roof. It removed
enough material to fill a wheelbarrow. The extension was also used to clean a very steep roof. I sat on the peak of the roof and reached down to both sides. Most of the material blew over the roof and beyond the gutters.
When using the machine on gutters that are not on walkable sections of roof, I am able to blow the material an average of eight feet from the edge of the ladder. This reduces the number of times that the ladder must be moved and climbed. I have done this same job with a gas powered machine. What a pain. Starting, stopping, stalling, noxious fumes, potential burns, using both hands to start it while balancing on a ladder. Everything is much easier with the battery powered machine, and the noise is greatly reduced.
Heavy, gucky material is still removed from gutters by hand but I don't try to make it a really clean job. I just grab the easy clumps and then allow the blower to blast everything along.
When I bought the chainsaw and blower, I assumed that the chainsaw would see much more use. So far, that hasn't happened. The blower has been used a lot. It's really handy having an extra battery and charger that match. On three occasions, I have completely killed a battery. A minute later, the battery was on the charger and I was back at work.
For use inside a building or for work that requires finesse, I still prefer the smaller and very controllable E-go machine.

This Greenworks machine is by far the best cordless blower for heavy wet material. For my purposes, using the machine commercially, I would say this was a good investment. For your average homeowner who only needs a blower occasionally, I would go with the E-go equipment that is available from Home Depot. Less expensive, high quality with a 5 year warranty and more user friendly.
