With so many cheaper dumbbells, the environment is just too testing. After a very short period of time the rubber will chip, crack, break and deteriorate. The handles will become loose and only tightening by gym staff every day will prevent the handle becoming unworkable. Whilst cheaper rubber dumbbells will be fine for personal and low use environments, a very hard wearing dumbbell like the Ivanko dumbbell is the only “Rubber” solution for heavy use commercial environments.
