I have had these for more than an year now and they are really good. They got delivered within a week and seems to do the job perfectly. Just a disclaimer that it starts leaving out dust or whatever it is filled with from sides very little if you have habit of clicking your Dumbells together.
Excellent for using at home. Plastic body (filled with sand most possibly) is prone to breakage if falls from hand. Although it has a positive side. Plastic body, if falls from your hand, will cause less damage to the floor tiles or your feet than a solid metal body would do. So, considering the budget, it is best for home use.
They arrived in perfect shape. Seem fragile so I'm keeping them in a padded box instead of keeping them in the open with the rest of my gym stuff. If you move them around, you can hear something like sand sliding inside them. The weight is perfectly balanced though and the grip is smooth. No complaints considering the price.
