These are very well made dusters. The fabric is slightly different on the two. The white one, which is a little longer, is made with shorter fibers which are more densely packed and the blue one has longer, more loose fibers. Both are excellent at picking up dust like they’re magnets for it. The white one has a long, flat base underneath the fibers while the blue is on a rod. The white one flexes some but stays straight, while the blue one can be bent to different shapes/positions. They switch on and off from the handle very easily with the press of a button. The handle is designed so that you can attach it to a pole for longer reach; however, you need a very specific pole for this. Most standard poles have threads at the end and this handle is threaded for that, however the design of the handle won’t work with all poles. I even have a pole from the same manufacturer as the as these dusters and it doesn’t fit – it has to be the specific pole from Unger. That’s the only reason I didn’t give these 5 stars.
