SMRTFT adjustable dumbbells provide a versatile weight range from 5 to 100 pounds, making them suitable for various fitness levels. Reviewers appreciate their compact design and quick weight adjustment feature, which enhances workout efficiency. However, some users have noted issues with the adjustment dial's durability over time. These dumbbells are ideal for home gym users seeking space-saving, functional equipment but may not be the best choice for those prioritizing long-term durability or aesthetic variety.
Full review
Weight range and adjustability
The SMRTFT adjustable dumbbells offer a substantial weight range that sets them apart from many competitors. This range allows for progressive training and accommodates both lighter warm-up sets and heavy compound movements. The quick-change mechanism operates through a simple handle twist, enabling users to switch between weights without the need for tools or complex assembly. The adjustability system is particularly praised for its smooth operation and tactile feedback, making it one of the most user-friendly adjustable dumbbell mechanisms tested. The ability to go up to 80 pounds represents a significant advantage over many alternatives that cap at 50 pounds, allowing for more advanced training without requiring additional equipment or add-on weight systems.
Space efficiency and storage
In home gym environments where space is at a premium, the SMRTFT dumbbells demonstrate exceptional efficiency. Users report that the compact footprint of these dumbbells allows them to maintain a full range of weights while fitting comfortably in small garage spaces or apartments. The design eliminates the need for large dumbbell racks or floor storage solutions, as the dumbbells can be easily stored upright or on a dedicated stand. This space-saving feature is particularly valuable for users who previously owned traditional dumbbell sets and experienced the challenge of storing multiple weights in limited areas. The cubic meter footprint required for a full 5-80 pound range is significantly smaller than what would be needed for a comparable traditional dumbbell setup.
Build quality and durability
The construction quality of these dumbbells is evident in their metal components and robust internal mechanisms. The plates are made from machined steel, giving them a substantial feel that closely mimics traditional dumbbells. Unlike some competitors that rely on plastic components, the SMRTFT dumbbells feature metal construction that provides enhanced durability. Users note that the plates have rounded corners which improve comfort during use and reduce the risk of injury. The internal adjustment mechanism is described as sturdy and reliable, with many users reporting years of consistent performance. However, the design does include a notable limitation: these dumbbells cannot be dropped without voiding the warranty, which requires careful handling during workouts. The knurled handle coating provides good grip even during heavy use, though some users mention it's not as aggressive as certain other brands.
Performance across training exercises
Users have tested these dumbbells across a wide variety of exercises, from basic curls and presses to complex movements like snatches and swings. The natural feel of the dumbbells allows for smooth transitions between different exercise types, with users noting that they perform similarly to traditional dumbbells during compound movements. The ability to perform drop sets is particularly praised, as the quick adjustment system allows for seamless transitions between weight levels during high-intensity training sessions. The weight distribution feels balanced during use, with no noticeable wobble or instability that might occur with less refined adjustable systems. Users report being able to maintain proper form throughout various exercises, including overhead movements where stability is crucial. The dumbbells perform well in both single-user and shared gym environments, though the shared usage scenario requires more frequent weight adjustments.
Value proposition and cost analysis
When comparing the cost per pound, these adjustable dumbbells offer compelling value. This pricing is significantly below the typical cost of second-hand dumbbell sets, which often average around $1 per pound. The cost efficiency becomes even more apparent when compared to traditional dumbbell rack setups, which would cost nearly three times as much for equivalent weight capacity. Users who previously owned traditional dumbbell sets report that the investment pays for itself quickly through space savings and the elimination of multiple individual dumbbell purchases. The value proposition is particularly strong for users who have limited storage space and want to maximize their training options without the expense of a full dumbbell rack. The two-year warranty provides additional protection for the investment, though users are advised to avoid dropping the dumbbells to maintain warranty coverage.
Limitations and usage constraints
Despite their many advantages, these dumbbells do present some notable limitations. The primary constraint is the inability to drop the dumbbells, which requires careful handling during workouts and eliminates their use in certain training scenarios like Olympic lifts where dropping is common. This restriction is particularly important for users who engage in high-impact training or have training partners who might accidentally drop weights. The maximum weight capacity of 80 pounds may not satisfy advanced lifters who require heavier weights, though users note that this is a common limitation among adjustable dumbbell systems. The need for a dedicated stand adds to the overall cost, though users report that the stand is a worthwhile investment for easy storage and adjustment. Additionally, the shared usage scenario creates challenges when training partners have different strength levels or training requirements, as frequent weight adjustments are necessary.
Strengths
- +Dumbbells offer a wide weight range from 5 to 100 pounds
- +Adjustment mechanism allows for quick weight changes during workouts
- +Compact design saves space in home gyms

Watch-outs
- −They cannot be dropped without risking damage
- −The 80lb model lacks a higher weight option
How it compares
The SMRTFT Adjustable Dumbbell offers the widest weight range up to 100 lbs, surpassing the Core Adjustable Dumbbells and Lifepro PowerFlow Plus. However, it lacks the rapid-change mechanism of the MX Select MX55 and has a more limited weight increment precision than the PowerBlock Elite. Unlike the Yes4All Cast Iron set, it's more expensive but offers better adjustability and durability.
Rating sources
“The SMRTFT Nüobell 580s have been one of our top picks for adjustable dumbbells for years now, and I've used them for over five. They're a reliable home training option that feel like the weights you'd find in a gym.”
“To put it simply, I love them. Sure, they're not perfect, and we'll get into why that is, but these adjustable dumbbells have completely changed my home workouts.”
“The value is insane since second-hand dumbbell rates are $1 per pound if you buy off marketplaces like Facebook. You're getting brand-new dumbbells for almost half the price of second-hand dumbbells.”
