Review: This is great when it works. But gets quite flimsy for weights exceeding 20kg. I’ve had this for 18 months, and the poor thing died after just doing KB swings with a 20kg weight. I can’t seem to find any information on a warranty. I think I’ll be looking for a more solid solution in future.
Review: This is such a great product idea for anyone who wants the versatility of different workouts without buying a bunch of separate equipment. This dumbbell converter is easy to put together and instantly turns dumbbells into a kettlebell. It feels solid during use and works exactly how a kettlebell should. Perfect for home workouts, especially if you are short on space but still want a wide range of exercises. Honestly, what more could you ask for?

Looks incredibly flimsy. They say it can hold up to 100lbs each but I won't try to swing them with such weight attached to it.
