Are adjustable kettlebells worth it?

Reviewers are split. Independent gear sites and verified buyers like adjustables such as the REP Fitness and BowFlex SelectTech 840 for saving space and money, but r/kettlebell threads repeatedly flag awkward balance on cleans, snatches and get-ups, plus durability concerns around plastic internals and open-bottom designs. They're best for space-constrained home gyms doing swings, squats and presses rather than technical ballistic work.
