Good quality dumbbells for home workouts. They feel sturdy, comfortable to hold, and the rubber coating is a nice touch for protecting the floor. The hex shape keeps them from rolling, and overall they’re easy to use and store. A solid choice if you want a basic, reliable set for strength training.

Great. Good grip just had a really strong rubber smell. But other than that it was worth it.

Did have a weird smell, but it gets the job done.

Great basic dumbbell set for myself, a novice lifter just graduating from my wife’s max 5 lb dumbbell set. The price was also less than similar weight sets.

I bought these to add to my matching set of 10,15,20,25s. I realized I needed some 8 pounders for my shoulders as the 10s were too heavy for me to keep proper form. Anyway, we aren't here to review my physique. These are great weights. They are the correct weight, I checked on my scale, and the rubber ends are the perfect size for how heavy they are. The handles are stainless and are very sturdy. They're a good size for wrapping my hands around, and I am a woman with relatively small hands. All of my other dumbbells are the same brand (purchased under a different account so I cannot review them here) and they are great. The rubber is nice for protecting my flooring, and protecting my head on those very rare occasions that I am not paying attention and bonk myself. Still hurts, but less so with the rubber than it does with the metal ones. I also had an issue where my basement was leaking and small amounts of water sat very near these dumbbells for an extended period of time, and they did not rust or get gross. The only "issue" I have with these dumbbells is that there is a residue that will come off on your hands/body the first few times you use them. This can be avoided if you wipe them down with an all-purpose cleaner before use. I usually just wash my hands after as I do not know what long-term effect cleaners might have on the integrity of the rubber. Overall a great product though and I plan to buy more of this brand as I need higher weights.
