I really wanted to like these dumbbells. I love the design and they work smoothly. I tried to overlook flaws. I'm not sure it's built for durablity. However, I ultimately returned it. (I'll include a few pictures here since Mikolo support ignored my emails.) Here is why…
The Dumbbells arrived with water in bags that wraps dumbbells inside the retail box under packing foam. Metal Parts on base bottom have rust which makes me worry about rust on internal components of Dumbbells that I can't see. Also, handles had several shards of metal shavings embedded in the rubber handles, one metal shaving almost 1/2” long. I removed what I could see with Tweezers. That is a safety concern. Workout Poster inside was deformed so unusable. Packaging had significant punctures. I sent multiple emails with pictures to Mikolo's “After-Sales” email listed inside the packaging material but I got NO response. I am concerned about longevity of the product, products safety, and the total absence of support by Mikolo. I am also seriously considering returning several other Mikolo products I purchased on Walmart and other platforms.
Walmart was awesome handling the return, though I did have to waste a lot of time lugging it to a FedEx store. Walmart was there to clean up where Mikolo support failed.
