## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to use, versatile
*by C***R on September 29, 2024*

I have used this adjustable dumbbell set consistently 3 to 4 times a week over the last 3 months. I was initially hesitant to buy it, but it has been worth every penny.I have used it mostly as an adjustable set of weights and kettle bell. Adding and taking off weights is pretty easy, quick and efficient.I also take body pump classes once a week, I transform the equipment into a barbell set and it holds up nicely.My adult sons also use my equipment for quick bicep curls, chest presses, weighted lunges etc.The rubber, plastic covered weights are a bit bulky but they are easy to store and do not scratch my wooden floor.I have advised all my friends to purchase this adjustable dumbbell set

### ⭐⭐⭐⭐⭐ KeppiFitness Adjustable Dumbbells – A Hit for My Home Gym!
*by M***A on February 24, 2025*

I’m super happy with these KeppiFitness adjustable dumbbells. They’re perfect for working out at home because they’re so versatile—you can use them as dumbbells, kettlebells, a bar, or even a push-up stand. It’s like having four pieces of equipment in one! The ability to adjust the weight is super easy and quick, letting me customize it for different exercises and gradually build strength at my own pace.They feel really secure and comfortable to use, with a non-slip grip that doesn’t slip even when I sweat. Plus, they don’t take up much space, which is ideal for my small workout corner. The quality is impressive—they’re durable, quiet when I move them, and the materials don’t scratch the floor. I’ve been using them for a month, and I’m still just as excited. They’ve helped me improve my workouts and feel stronger. Highly recommend them for anyone looking for a reliable and versatile piece of equipment for home training!

### ⭐⭐⭐⭐ Works Good, It Can't support 90lbs
*by C***N on March 19, 2025*

Bought the 90 lb barbell. It can not In fact support 90lbs. The brackets WILL break. You can go up to 72lbs total with no issue. I'd say buy the lower weight since the 90lbs doesn't work. Don't go with the higher weight unless you just want more individual weights for the dumbells. Otherwise, great if you can't make it to the gym for the heavier weights and good versatility.
