The smarter adjustable dumbbell buy: BRAINGAIN 24kg or Yaheetech 18kg?

Display

This category doesn’t apply in the usual sense, since neither product has a screen or digital interface. If you were hoping for smart features or rep tracking, neither set offers that. Winner: tie. The real equivalent here is how clearly the weight changes are labelled and how confidently the adjustment mechanism feels in use.

Performance

BRAINGAIN wins here decisively. Its 24kg per dumbbell ceiling gives you a far more usable training range than Yaheetech’s 18kg per dumbbell limit, and that matters a lot for compound work like presses, rows, goblet squats, and RDLs. The BRAINGAIN set is also marketed as 15-in-1, versus Yaheetech’s 12-in-1, which suggests finer progression and more flexibility between light accessory work and heavier strength sets. For a growing home gym, 18kg can feel limiting surprisingly quickly, especially for men or anyone already training seriously.

Build quality and design

BRAINGAIN also takes this category. The higher review count and stronger rating are meaningful: 4.6/5 from 1,234 reviews is a much better confidence signal than 4.2/5 from 393 reviews. Both advertise non-slip grips and safety locking systems, but BRAINGAIN adds a secure locking system and includes a storage dock, which is a practical bonus for keeping the pair organised and reducing the chance of mishandling loose plates. In real home-gym use, a better dock and a more refined quick-change system usually translate to less faff and a more premium feel. Yaheetech is likely perfectly serviceable, but it reads more like the budget option.

Battery life

Not applicable, as neither product is powered. If you were looking for a smart dumbbell with electronics, these are purely mechanical adjustable weights. Winner: tie.

Price and value for money

Yaheetech wins on upfront price, but BRAINGAIN wins on value for money. The Yaheetech set is £169.99, saving you £28 versus BRAINGAIN’s £197.99, which is not nothing. However, that saving buys you less weight, fewer adjustment options, and a product with a lower average rating. In strength equipment, the cheaper option is only better value if it still meets your needs for long enough; 18kg per dumbbell is more likely to be outgrown, while 24kg gives you a much better return over time. If you want to avoid replacing kit later, BRAINGAIN is the better investment.

Game library/features

Again, not applicable in a literal sense, but if we translate this to feature set, BRAINGAIN wins. It offers a 15-in-1 adjustment format, a higher maximum load, and comes with a storage dock. Yaheetech’s 12-in-1 setup is simpler and cheaper, but it has fewer usable increments and less headroom for progression. For home training, “features” should mean practical flexibility: how many movements it supports, how fast you can change weight, and whether the system stays secure under repeated use. BRAINGAIN comes out ahead on all three.

Overall user experience

BRAINGAIN is the better all-round experience for most buyers. Adjustable dumbbells are supposed to replace a whole rack of fixed weights, and the 24kg pair does that more convincingly than the 18kg pair. The higher rating, larger review base, included storage dock, and stronger weight range make it the more complete home-gym solution. Yaheetech may suit occasional lifters or anyone on a tighter budget, but the lower ceiling means you’ll hit its limits sooner, especially for pressing and lower-body accessory work. If you’re building a serious home training space and want a set you won’t quickly regret, BRAINGAIN is the safer, more future-proof choice.

Overall summary: Yaheetech is the cheaper entry point, but BRAINGAIN is the better dumbbell set in every way that matters for training quality, longevity, and resale-minded value. Unless your budget is tight and you know 18kg per hand is enough, BRAINGAIN is the one to buy.
