This perforelieur done what is expected of him. No more, no less. Everything is done relatively simply in the sense that there is no need to read the manual hours. It raises the lever, perforated, then inserts spirals away and it's done. The camera is not too light, it remains stable and does not cause an accident. However I put a big downside for the lack of material provided since only the machine. No spiral charging. It would not have seemed so unlikely yet. Apart from that, the machine does what is asked without blinking and there is the main thing.
