There here have pages and pages of reviews were posted, I want time limit on what bothers me. After a few hours use, it starts here to squeak and creak there on. Of course, the device is exposed to some stress, so I do not want negative values when times the screws have to be tightened against the creaking every now and then. But the squeal. So I removed all the plastic protective caps (and reduced left) and spray more or less regularly some oil on the moving parts and have again a few hours of use rest, in the truest sense of the word. Here you should provide something of home in my view, to ensure noiseless operation (grease nipples?). Incidentally, you can also practice patience when "warmed up" the device is, can the squeak without Regrease significantly. I did not have the patience.
