For the weights of dumbbells you can get along with the durability (I feel like I can drop these from whatever height, not that I do though), the price is pretty much unbeatable. They are quick-lock but not quick change, so if you do a lot of dumbbell work each day with various weights, you will likely get annoyed quickly (spend some money on the Reppins then). However, if you're using dumbbells for one or two exercises per training session, they are absolutely fine with changing weights. Plus, with their size, they are often shorter then lots of traditional dumbbells which helps with a lot of exercises to increase range of motion. If
