Perfect little set of weights
Style: Sage 5lb Pair
I really like these dumbbells for at-home workouts. The neoprene coating feels soft but secure, so I never worry about them slipping. They don’t clank around or chip like some metal weights I’ve owned in the past, and the flat edges keep them from rolling on the floor. I’ve used them for strength training, arm toning, and even light physical therapy exercises, and they’ve held up perfectly. The color is bright and makes it easy to find the right pair quickly. Great quality for the price, highly recommend!

Exactly what I was looking for
Style: 56LB, 10 pieces with rack
Exactly what I was looking for. The colors are super cute and the quality of the set is just as expected. It’s a perfect size and sits out in the open in my living room for convenience in a corner as if it belongs there. I just love it.

Great Gift, Mom Loves Them
Style: 12lb, set of 6 with stand (Rosy Vigor)
Bought these as a gift for my mom and she really likes them. The neoprene coating feels comfortable to grip, and the weights are easy to handle and store. They look nice and feel well-made. A simple, thoughtful gift that she’s actually using - always a win.

Everything is perfect, minus the color bleeding
Style: Purple 3lb Pair
I love the feel of these in my hands, and the color selection! I only give 4 stars because if you have different colors touching (when they’re putting away) the darker colors will rub onto the lighter colors. My light green 5 lbs have stains from the purple 3 lb ones, so now I keep them spaced or out parchment paper between. I have OCD about these things, so it either may not matter to others. But if it does, keep them separated haha.

Light weight and easy to workout with.
Style: Rose Pink 1lb Pair
These small dumbbells are great for bicep curls, triceps extensions, lateral raises, and overhead presses. I cant lift heavy objects so these are perfect for me.
