This is a cheaper alternative of the Mèffert’s version. The design of the pieces appears to be the same, but the overall quality of this puzzle is worse. The rounded edges and turning are OK, but some center caps are very loose, they fell off during solve (needed to be fixed "manually" at the end). The stickering is not precise enough, so some of them started to peel off / to be damaged at a few edges during the first solve.
