We use quite tall bottles and labels, so setting up the machine was a challenge. The assembly itself, as well as using the device, requires some technical knowledge. After making structural corrections to technical errors, it is ready for use, and when it does work, it is really fast. The microswitch starts itself, so sometimes the machine makes one empty revolution after lifting the lever. In general, it is possible to work on it, although personally I would use slightly different materials to increase the accuracy of gluing labels and also to guide the paper.
