Pros: 1. Affordable 2. Genuine 3. Great for beginners 4. Easy to store Cons: 1. It isn't very durable (you need to treat it very very gently, then and only then will this product last for a long time.) 2. The caps tend to move a little on the dumbbells if you hit them on any hard surface which cause a minute amount of sand to leak. (Not enough to reduce the weight of the dumbelle but it really is annoying when you're bench pressing and you hit the two dumbelles on top and a few grains of sand fall in your eye) All in all, go for it if you're just starting at home and don't know if you want to invest your time and money in the gym yet.
