Hi Chris. It is a pretty good focuser. Not great by a long shot, but for the money you'll definately wonder how you did without it before.
My only complaint with it is the amount of backlash in it when switching directions. For visual work this isn't much of a problem, but when using it for astrophotography and using it in conjunction with some focusing programs that have the ability to autofocus or count the focus steps it can become a bit of a nuisance. I never checked, but it may be possible to adjust the focuser to remove some of the backlash, but from memory one (or two?) of the gears are nylon/plastic so I don't know how they would tolerate being meshed together tighter.
