At SMRTFT, we only sell the most innovative, highest-quality fitness products on the market. SMRTFT NUOBELLs feel like traditional dumbbells. They have comparable knurling (the horizontal and vertical crossing lines on the handle). We aim for a mid-range knurling feel. The size of the dumbbells, at any weight from 5 to 80 lbs, is similar to those you find at your local gym. Also, we arrange the plates so that you don't have a bar sticking out the end, no matter the weight. Many other adjustable dumbbells are designed differently and feel "weird" for seasoned weight lifters.
