Weakness is the detachable handle, which can be completely separated above the centering of the base plate. The connections for the various switches in the handle are made via spring-loaded pins that probably do not always get optimal contact. The first stick the Coolie Hat was not functioning, the second there were several switches that could be persuaded only after repeated disassembly and reassembly to cooperate.
The often criticized stability is actually fine. Forward this is something small, but bearable. If that total is to kippelig can buy here small clamps for fretwork Amazon making it possible to fix the stick eg on a tabletop.
Conclusion: Actually a solid stick with enough buttons. One star deduction for the contact problems otherwise recommended.
