Lightweight castle, ideal to make things easy to block, if no big security is needed. The castle is light and small enough that it can be accommodated without problems or in each pocket. The colorful Metalliklakierung makes it clearly visible for example in locker rows in gymnasiums. The combination can be changed easily.
The maintenance is safe does not seem without tools and a lot of effort to crack. As a combination lock, it is of course be opened by trial and error.
Some blemishes but there are: the number wheels lock into place with a slight resistance, so they are often a little too far / short turns. Until you get used to the right point, frickelt you the first few times around a little. In addition, the striker marked play of about 0.5 - 1 mm. Bring to the castle for transport to a pocket or on a shutter in movement, it is accompanied by a noticeable rattling.
Overall, a practical lock if no big security needs (as a combination lock always openable). The weaknesses are for the price perfectly okay.
