FAQ's
Q: How do the Stealth adjustable dumbbells work?
These dumbbells feature an innovative system that lets you select your desired weight with a simple turn of the handle. The adjustable mechanism securely locks the selected plates in place when out of the base, you then release and allow adjustment when in the base, allowing you to transition between different weight settings quickly and efficiently.
Q: Are these dumbbells suitable for beginners?
Yes, the 41.5kg/32.5kg/23.5kg Premium Adjustable Dumbbells are suitable for all fitness levels. The adjustable weight range allows beginners to start at a lower weight and gradually increase resistance as they build strength, while more experienced users can utilise the heavier settings for advanced workouts.
Q: What exercises can I perform with these dumbbells?
These dumbbells are highly versatile and can be used for a wide range of exercises, including bicep curls, tricep extensions, shoulder presses, chest presses, lunges, and more. They are ideal for full-body workouts.
Q: How long is the warranty
Our standard warranty is now 2 years but can be extended to 3 or 5 years for extra peace of mind
Q: What is included in the warranty
- Our warranty covers any issue caused by a manufacturing defect or any issues based on the production or transportation of the dumbbells.
- The warranty is non-transferable and only covers the original purchaser. Coverage ends when the product functionality is affected by issues outside manufacturing defects or the owner is transferred.
Q: What are the differences between the Premium Adjustable Dumbbells and the Black Edition?
- We have overhauled how the plates work with the black edition dumbbells, this enables a more precise fit, less metal-on-metal noise and an improved user experience. On the other side, the full metal construction of the Premium Adjustable Dumbbells gives a more robust design with a durable electroplated finish
Q; Why choose adjustable dumbbells over fixed round/hex dumbbells
- 1. Less Space needed: to fit 26 pairs of dumbbells you would need a magnitude more space than a set of stealth adjustable dumbbells, 2. More Weight Increments: stealth adjustable dumbbells have 1.5kg increments across the range but most fixed weights only go up in 2.5kg, 3. More budget-friendly: the cost of a full set of an equivalent weight range would cost around 4x as much as a set of stealth adjustable dumbbells.

I've been growing ever tired with my spinlock dumbells over the last 5 years so thought it was time to splash out on something that would mean I'm more likely to jump up weights rather than thinking "ah, I can't be bothered to change them for one set".
These dumbells are great, it's seconds to swap between weights and it couldn't be easier. They're well made and there's not really much give in them if you try to rattle which is a nice surprise. I've had them over a month now so they've had plenty of use and they're still in perfect condition, no scratches or chips.
Two small downsides, one of which could be solved quite easily I think. The knurling is basically non existent, you can tell there's something there but it's borderline just a smooth bar. I'd like this to be a bit more aggressive. Second problem is they can feel a bit unbalanced at times thanks to that 0.5kg disc, I don't notice it all the time but on some shoulder presses for example you can tell there's a little imbalance there.
Overall, they're expensive but I have no regrets so far.

The stealth adjustable dumbbells are very good. They look good and are good. I pondered many different brands, researching online with YouTube and video as well as AI. Many things pointed to USA brands which was good for general review but impractical for ordering. I came across a few UK companies. All at various price points, review and such.
My first port of call was to obviously review features and weight against price. Then my second was to reach out via an email/message to see which companies were responsive and helpful. Boom that’s where AssassinGoods came out unbelievably better, some others didn’t even get back to me.
So good communications within within a few minutes I think.
I decided to order. I’m not disappointed.
They look great, they feel great. I unboxed and jumped right in using them with ease, comfortable grip, easy and felt secure to change weights. They feel solid. I shook them as well to see how much rattle there was, barely any.
I cannot talk to the long term durability given that it’s day 0 of having them, but with email communications rapid on pre sales, I can only hope the same post sales, nothing to suggest otherwise. Similarly with all the spare parts online it gave me comfort.
Glad I chose these now that’s for sure! If they are at your price point, I’d recommend these!

Really pleased with the quality of these dumbbells. I am only a beginner and at the low end of the weights but these will take me on the whole journey and then some. Was really pleased how quickly I could change the weight in a 20 second rest between exercises. Definitely recommend
