Consumer Reports

Of all hand weights we tested, the Nice C Adjustable weights are our most comfortable grip for all hand sizes as well as provide the most compact storage for an adjustable weight. With a grip width of 5 inches and a grip circumference ranging from 4.9 inches at its narrowest up to 6.5 inches at its widest &#40;thanks to its hourglass shape&#41;, the Nice C Adjustable weights provide ample space for all types of hands with a comfortable neoprene grip. We found this to be a rare feature among the small weights we tested, many of which only fit small to medium-sized hands. As an adjustable weight with up to 5 different weighting options, the weights have a relatively small footprint of only 5.75" x 9.5". The unique weight adjusting design allows you to unscrew the ends of each weight and either add or remove metal weight bars, each weighing about 0.55 lbs. Foam inserts included with the set can be used in place of the metal bars to help reduce noise and internal shifting if each weight is only partially loaded. Each metal bar was pleasantly accurate when weighed on our scales as well. 
Technically, the Nice C Adjustable weights are a 5-in-1 weight set. However, if you want both ends of each weight to be balanced and weighted evenly, they really are a 3-in-1 weight set with 2.3, 3.4, and 4.5-pound options. The range is limited, with only a 2.2-pound difference between the lightest and the heaviest options. There is also no indicator on the weights themselves or the weight bars to decipher what weight you are currently working with. It also takes about 30 seconds to adjust both weights, which can interrupt the flow of your workout. The hourglass shape allows the weights to roll readily on hard surfaces. The soft neoprene does provide non-marking traction along the weights' outer edges, but the soft material and light grey color show grime easily and attract dirt and sand in outside settings. Overall, these weights are a low-priced introduction into adjustable weights, with the space-saving convenience these designs bring. More versatile than buying a single pair of dumbbells with a fixed weight, the Nice C Adjustable weights are a great introductory weight set with small incremental adjustments suitable for novices and those looking to tone muscle or maintain strength through high repetition exercises.
