"Can't complain"
Only just bought this (not actually used with piping bag yet) Doughnut day today instead lol but seems to extend, collapse & clip together fine to me, some reviews saying its a bit flimsy sure It's not exactly the thickest plastic but personally I cant see what's wrong with it & its only a tenner, what more do some people expect, the only thing I would say once the sections are locked, just rotate using the base & not holding the cone sections of they "might" unclip
