Great Set
Color: Multicolor, Size: 146 LB
This is a great set of dumbbells. I was looking for the weights in this set and I wanted a nice rack to keep them off the floor. So far they feel solid and accurate and are working as expected. The reason for 4 stars and not 5 - The (2) 20 pound dumbbells shipped separate, which was fine...but everything else was in 1 box! That's 106 pounds plus the rack and packaging. The delivery guy struggled and almost dropped it, and then I had to move it from my front door step. How much more could it cost them to ship it in 3 boxes or redistribute it into 2 boxes under 100 pounds? So lucky the box didn't drop and the contents get lost or wrecked. Otherwise it is a great set!

Great weights !!!

VERY HEAVY box. These are great weights that are not rough on your hands. Putting together the stand was simple and makes the storage simplified.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.
