Great dumbbells, look good and delivered on time. I would recommend them to friends and family.

Easy clear website. Pricing and journey through the purchase was trouble free.

The product arrived quickly and well packaged. And it was easy to assemble the stand.

It's early days, but my initial impression is that I bought the right brand.

The black edition seam well made, are definitely easy to use and change weight, feel tight and the handle diameter and knurling is just right.

And they happen to look good too...

Incredible adjustable dumbbells

Really impressed with the Assassin 41.5kg adjustable dumbbells. Build quality is excellent, they feel solid and well-engineered, none of the rattle or looseness you get with cheaper adjustable sets when you're moving through reps. The locking mechanism is tight and secure at every weight setting.

Customer service was great too - quick, helpful responses when I had questions. Would definitely recommend if you're looking for adjustable dumbbells that actually feel gym-quality at home.

I Recently bought the Stealth black 41.5kg adjustable dumbells.
Delivered within a few days of ordering.
I set them up in just a few minutes
Really smooth mechanism, and no more herding loose weights around my tiny living room..
Saving up for the stand now.
Thankyou Assassin, I love this system.

I’ve had the adjustable dumbbells and kettle bells for several weeks now and so far so good.

Recently bought the new Stealth Adjustment Core Edition 40kg Dumbbells and have been very impressed.

Delivered quickly, well packaged and really easy to set up.

Smooth to change weights (my 10 year old can do it) and they feel great in your hand.

Exactly what I wanted and hoped for.

I ordered the Adjustable Chrome dumbbells 41.5kg and they are utterly brilliant, exceeding my already high expectations. The easy-adjust mechanism is great, the build quality is very high, and they're stylish in the home. 10/10 product, and the shipping packaging is great too - no dents or marks.

Alongside the product, I want to highlight how brilliant the customer service from Samuel and Mike is too. There were issues with the delivery (all caused by the courier and not Assassin Goods themselves), but Samuel and Mike were supportive, very quick to reply and keep me updated throughout. They really went above and beyond to make sure I received the order.

I have no hesitation in buying from Assassin Goods again, and I'd definitely recommend to friends.

I ordered my Chrome Edition 41.5kg adjustable dumbells on Saturday 11th July and they arrived promptly on Tuesday 14th July. Communication was excellent throughout.

I proceeded to set them up and as a person not DIY minded even I found it easy enough.

I have used them twice already and my initial impressions of the dumbells are that they are of excellent quality. The adjustable mechanism is smooth and the feel when lifting just feels right. Experienced lifters will recognise that some dumbells just feel awkward when lifting but these do not!

I would definitely buy again from Assassin Goods.

Amazing quality , so well made and superb build . Very very happy

Very well packed. Came very quick. Lovely looking weights. Didn't expect them to be so big though. Thought they might have been slightly smaller and it really surprises me how little the weights are but are heavy. They are incredible. Thank you very much indeed. Hope to buy in the future. Thank you once again 😁

I ordered their adjustable dumbbells on 11 May 2026 and requested a change in order the same morning (from core to premium black), very responsive - answered my call at 7:30. Order arrived on 12 May 2026, quick next-day delivery! One plastic part was damaged and I called for a replacement part which was delivered on 15 May 2026 - again, responsive customer support and quick delivery. I managed to fix the dumbbells by myself after instructions over a call. Great quality dumbbells to start my strength training journey. Highly recommend this company!

My daughters bought them (41,5kg pair) for me for my 50th birthday. Received them two days ago. Used them for the last two days work out. Amazing dumbbells!

I originally gave the Stealth Adjustable Dumbbells 41.5kg Chrome a 5-star review because the dumbbells feel solid, heavy-duty, and the quick weight adjustment system works very well.
However, after more use, I noticed a serious safety issue. The edges of the dumbbells are quite sharp, and during training I accidentally cut my leg badly enough to cause an injury. I have included a picture of the injury.
The dumbbells still feel high quality overall, but the sharp edges definitely need improving for safety reasons, especially during close-contact movements or when training in tight spaces.

Ordered the Adjustable KB bundle on 1st April and it arrived the very next day. Extremely efficient, professional, and friendly service. The products are high-quality and built to last. Highly recommended!

Parece de muy buena calidad y una compra acertada por el precio que tenía con la preventa ,ahora toca darle caña para ver cómo responden

Ordered an adjustable kettlebell from stealth (also 5 stars by the way, usable straight out of the box and super solid). Want to give Assassin a shout out though as DPD pulled a howler on first delivery, after trying to deal with them they were no help at all, I contacted Assassin and they offered second to none customer service. Clearly they are lovely people, who sell the best of the best gear. Next time I need more home gym equipment I'll be back. Thanks team

Not happy with this company. I pre-ordered kettlebells from them, paying upon order. Their pre-order policy is quite clear that any order can be cancelled at any point before despatch for a refund. Due to a change in priorities, I sent an email requesting a cancellation at 06:57 on Tuesday - the kettlebells were still listed as pre-order on their site at this time. I heard nothing, so sent a chaser at 19:14 that evening. I heard nothing until 21:30, when I received an automated email telling me my order had been despatched - the kettlebells were still listed as pre-order on the website! I refuse to believe my previous emails (particularly the one sent at 06:57) had not been seen prior to despatch - I believe it was deliberately ignored in order to prevent me cancelling. Do not trust this company!

UPDATE: I have been given the option of returning the kettlebells, however due to the cost of returning 40kg of kettlebells, plus the fact I would then have the cost of initial shipping deducted from my refund amount, I'm better off keeping them...

La mejor compra para un gimnasio en casa, son perfectas, todo lo que puedo decir es positivo.

Even though I placed my order on 8/02/2026 Sunday night, it was delivered on 10/02/2026. The dumbbells were well packaged and very easy to assemble and quite easy to change from one weight to another. Great addition to any personal gym.
