The Pros

Each dumbbell features 9 weight settings that increase in 5-pound increments ranging from 4 pounds to 45 pounds. Some other adjustable dumbbells only have 1 dial that changes weight, but these dumbbells have a dial at either end—and the exerciser only has to move one dial to change the weight instead of both. All of the weight increases are housed in a single dumbbell, so exercisers do not have to have an entire shelf full of traditional fixed-weight dumbbells. In fact, users who wish to do multiple types of exercises during one workout can simply adjust the dials on the adjustable weights rather than switching out individual traditional weights. A workout guide is included with the dumbbells and stand and includes a 1-year warranty covers both the adjustable dumbbells and the stand.

More Pros:

  • These dumbbells are more durable than some of the other adjustable dumbbells on the market that have more plastic parts that break more easily.
  • Both the weights and the stand are easy to assemble, bypassing the assembly-caused headache that is often the result of putting together other pieces of exercise equipment.
  • Two of these Universal Power-Pak Adjustable Dumbbells replace 18 individual fixed-rate dumbbells (or 9 sets of fixed-rate dumbbells).
  • The no-slip handle is well-made and is constructed from thermoplastic rubber, offering exercisers a firm grip.
  • The price of these dumbbells is right—especially in comparison to other flashy but less durable models.
  • Exercisers can do more than 30 different exercises with these dumbbells that can strengthen a variety of muscles.
  • The variety of settings available makes this dumbbell set ideal for amateur and experienced weight-lifters alike.
  • The ergonomic stand is the ideal height for quick use and easy access; users can adjust the weight levels of the weights while they are resting on the stand.

The Cons

The most frequent complaint about these Nautilus Universal dumbbells center around the fact that these weights slide a bit when in use. Exercisers complain about both the noise these make when the weights slide and a feeling of insecurity about the security of the weights. The next most frequent complaint is that the plastic components of these weights can break fairly easily after basic use. Sometimes exercisers end up dropping weights due to muscle fatigue, so having weights that could break when dropped might be a deal-breaker for some.

These dumbbells—like many other adjustable dumbbells—are larger than many traditional dumbbells, so some users may have a hard time doing some of the exercises due to the size and bulk of the dumbbells.

Some reviewers find the aesthetics of these dumbbells and/or the stand to be unappealing because they are more hexagonal than round. Reviewers also felt that adjustable dumbbells offered by other brands are more aesthetically appealing than these.

The Verdict

Most of the flaws of Universal Power-Pak 445 Adjustable Dumbbells can be dealt with or addressed easily. While many reviewers commented on the clacking, sliding noise these weights sometimes made while in use, these reviewers also often said that the noise itself did not decrease the effectiveness of their exercise routines. Proper form and extra care during the exercises can offset the problems caused by weight size, and merely having the appearance of cheapness does not mean materials will break. The 1-year warranty on these adjustable dumbbells will cover fixing any parts that break during that period. Aesthetic appeal is a matter of personal taste, so exercisers will have to look at several models and decide such things for themselves.

Many of the Universal Power-Pak Adjustable Dumbbells’ users rave about the ease of adjusting the weight levels and the fairly low price, but for $10 more on Amazon.com, exercisers can check out Bowflex SelectTech 552 Adjustable Dumbbells. These adjustable dumbbells are more aesthetically appealing and are rated higher on Amazon. Weight can be adjusted in 2.5-pound increments rather than 5-pound increments and the overall weight of each individual weight can be increased up to 52.5 pounds. Consumers should be advised, however, that these Bowflex weights have, in some cases, fallen apart during use, resulting in multiple injuries. For all Power-Pak 445 user’s complaints about sliding, noisy weights, few of them can complain of weights actually falling off causing injury.
