At SMRTFT, we take durability and quality seriously. They are both values that are extremely important to our company and culture. After extensive Flexural Strength Testing, we can say that the resistance and durability of the type of plastic we use is actually stronger than cast iron.

Look-a-likes are using old 32kg twist technology, which cannot handle more than 32kg (70.55 pounds). Some counterfeits honestly state that their dumbbells are 70 pounds. However, many manufacturers instead claim that their weights are 80lbs when they are only 70lbs. Worse, some manufacturers add 80 lbs with the old technology. This is unsafe and dangerous.

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.

We thoroughly research and design our product and only sell top-of-line fitness products. SMRTFT NUOBELLs are designed to be highly durable under non-commercial use. We understand our community might think this because the weights adjust so seamlessly. But, with regular use, the SMRTFT NUOBELLs last for years. It should be mentioned that similar to other adjustable dumbbell products, we do not recommend dropping or slamming the dumbbells. If you have any concerns about how your NUOBELLs operate, simply reach out to our Support team with photos and/or videos of your NUOBELLs, and we're happy to help! You can add 1 or 3 years of our SMRTCARE Extended Warranty on top of the built-in 2-year Manufacturer's warranty that comes with your purchase.

We absolutely recommend the stand that is custom-made for the NUOBELLs. As with all SMRTFT products, they have been designed to be the best on the market. Every time you pick up and set down your weights, you could be placing down as much as 160 pounds. Our stands can withstand that weight time after time. We also design the stand to be at the perfect height for you to not have to put improper strain on your lower back. The stand also has rubber feet that do not scratch or mark your floors.

SMRTFT NUOBELLs are a space and time saver. They make your home look better and provide a more efficient workout. You do not need to buy many different dumbbells to have one workout. In fact, when you consider the cost involved with buying multiple weights, SMRTFT dumbbells are frequently a much less expensive investment. When comparing NUOBELLs to other adjustable dumbbells, you never have to worry about storing extra plates or taking plates on and off loadable handles, as these adjust at the twist of your wrist! All unused plates stay situated in their cradles. To adjust to a new weight, simply place the dumbbell back into the cradle, and twist! These provide a much more efficient, aerobic workout than loadable dumbbells. We are here to help you get stronger and fitter in a more effortless, more efficient manner!

In our experience, we have plenty of customers who use SMRTFT NUOBELLs in CrossFit type environments. We are always here to help you get fit and more muscular in the way you most enjoy doing so! But, we need to mention that our adjustable dumbbells should be set or placed down instead of dropping or throwing them down. We're hoping you're not throwing around any brand of 80-pound dumbbells! If you remain in control of your weight selections, these will last!

SMRTFT NUOBELLs are designed to hold the round plates on the dumbbell in multiple ways. First, the handle extender extends through the middle of the plates. Second, the tongue-and-groove system at the top and bottom of each plate, where connectors interlock to secures the plates to one another. We recommend that you check that everything is set up properly prior to starting a workout with any equipment you use to get stronger.

The plates are securely interlocked, but there can be small movements when the dumbbell is in use.

You might be reading a review of a knockoff, but our SMRTFT NUOBELLs weigh as advertised, 50 or 80LB.
