In principle, an optimal idea, especially for wood and craft work and if it does not really matter to the tenth of a millimeter:
+ Many functions, incl. Marking of circles and parallels and concealed hinges and rows of holes for shelves,
+ Parallel shift
+ Reversible.
Unfortunately, the part Wolfcraft not thought consistently, and the price is considered more important than the quality:
- Poor quality in materials and workmanship: paint residues, sharp edges, hard-to-use stop rail, no flatness of the angle, not solid leg
- Dimensional inaccuracy in good ± 1mm,
- Scales untenable because not milled or etched but only printed, and is not necessarily accurate,
- Problems with the right angle.
Actually, I wanted us to "treat" the 500mm angle, but due but some problems (especially in the dimensional accuracy) I refrained from because nothing is more annoying than eg wiggle the shelves because the 4 holes do not agree among themselves.
Conclusion: Despite still, since he does not necessarily cost a fortune, a conditionally usable angle, especially for handicrafts
