Are cheap Amazon weighted vests (ZELUS, BAGAIL, Poudee) actually any good?

For walking and light cardio at 10–20 lbs, the community consensus on r/walking and r/BestBudgetFindss is that budget vests like ZELUS and BAGAIL are perfectly adequate and comfortable. Reviewers warn against them for heavy rucking or jumping/HIIT work, where stitching, bounce control, and weight distribution become real problems — that's where dedicated rucking vests from GORUCK, MVRK, or RUNmax pull ahead.
