I have been satisfied with its performance, it meets my needs perfectly. The feature with the speed adjustment is very convenient because sometimes you don't want intensity or noise while performing a cleaning task, so you can adjust the revolutions accordingly. The only downside is the fact that the power button spans the entire bottom area of the handle, so during transport, when holding it by the handle, whether you want to or not, it almost always gets pressed and if you have the battery attached, it activates, so you either have to hold it by the nozzle of the blower or you have to remove the battery every time.
