BrainGain Reviews 

Great bit of kit delivered and well packed. Adjustable dumbells, been in use for 7 months now, working perfectly.

Purchased the 40kg adjustable dumbbells which unfortunately arrived damaged. Contacted Sultan in BrainGain customer service who handled the issue fantastically well, replacement part shipped and arrived in 24hrs. Excellent

The product itself is marvelous! Got the 41.5 kg in black with stands. Incredible upgrade to my Bowlfex which maxed at 52.5lbs. The instruction manual could be slightly improved in two areas [(1) when to use long vs short bolts and (2) how to identify and exactly install the outer weight plates] but could figure it eventually out myself.

I bought a pair of factory returns dumbbells from these guys for a bargain price. They were still in box and unused.

When I got them home, the change mechanism was sticky. I thought I'd messed up because as returns, I thought it was basically on me to take the risk.

Not so. Contacted the company and they couldn't have been more helpful. At no inconvenience to me, sent an engineer to my home (who luckily lived close by) who tested, assessed the dumbbells and gave me a replacement pair there and then.

Replacement pair have been in use now for 5 weeks now and are brilliant.

These guys are serious about customer support and it shows.

Seller was very helpful when I communicated with them,fast response and will buy again from them.

BrainGain were very helpful and sourced me a part at a good price for an older dumbbell that was out of warranty, Sultan was very helpful and responded quickly to all of my questions. I was very impressed with the service I received. Thank you.

It all started with a delivery issue: the order was split into 4 packages and only 1 was initially received, while the others were incorrectly marked as delivered.

The customer support was very reactive and cooperative throughout the entire process. Special thanks to Sultan, who handled the case professionally and arranged the reshipment of the missing packages quickly.

Now that everything has been resolved, I can also say that I’m very satisfied with the product itself. The quality is good, solid materials, and clearly above many cheaper alternatives on the market. It’s an investment, but definitely worth it for long-term training. A great addition to a home gym.

I bought 24kg adjustable dumbbells and they are brilliant! I wish I had invested in them before now. Initially I was worried they would be too bulky but they’re absolutely fine - even for females. The change between weights is smooth and is literally just a click. I had an issue with a discount code not working, but after contacting Braingain, Sultan replied promptly and arranged for the discount to be refunded. Definitely recommend the weights and the customer service.

Ordered the 24kg adjustable dumbbells. Shipped separately, arrived promptly. I queried the delivery process and was dealt with promptly by Sultan. No complaints so far.

I got the 4-41.5 dumbells, good product, helpful support when i put in the wrong address

I would like to update my previous review, as the situation was ultimately resolved completely and correctly.

Yes, there were complications with logistics and UPS shipping during delivery, which led to delays and returns. It was indeed unpleasant and took longer than expected.

However, I would like to separately note the work of BrainGain's support service, in particular manager Molly. Throughout the entire process, they kept in touch with me, explained each step in detail, and sincerely tried to help.

As a result, the issue was successfully resolved, I received the goods, and everything corresponds to the order. The company fulfilled its obligations, and communication with the customer was honest and respectful.

Mistakes can happen in any international delivery — what matters is how the company corrects them, and here BrainGain showed its professional side.

Thank you for your support and responsibility.
Sincerely,
Vladimir

Had a query on how to get a new product up and running that I just purchased - a walking machine. Zain dealt promptly with my query and gave me the required instruction so it was all up and running in no time at all. So many thanks for the prompt customer service.

Fast and easy service, super quick delivery, recommended

Sultan. Absolutely incredible, got the 24kg adjustable pair through Amazon and the dumbbells themselves are fantastic just a shame that the courier managed to break the tray on one of them to smithereens 😂 reached out to brain gain for support letting them know about what had happened during shipment, was met with a lovely email and they have sent me a replacement tray, Sultan was very very kind and helpful. Definitely will be purchasing through here again :)

Support was quick and helpful. I ordered weights from them and the delivery was delayed. Sultan was very supportive and took care, that everything arrived.

I ordered the 12.5kg adjustable dumbbell and it was delivered fully assembled the next day. The product itself is of excellent quality and an absolute genius invention. I love how you can change the weight in literally 1 second, it's like magic and I'm beyond pleased. I also received great service from Hassan who answered all my queries in a friendly and efficient manner. Thank you 😊

Super smooth, the whole process. From purchasing to delivery. And the products are top class. I purchased the adjustable dumbbells and bench press and they’re both so slick to use. Honestly biggest game changer. Don’t take up space and actually look great in my flat. And so easy to adjust.

Brilliant customer service, the dumbells were exactly as advertised, easy to use and warranty supplied also. They also offered if i wanted to upscale to do a full exchange if wanted, good people.

Cheers guys.

⭐️⭐️⭐️⭐️⭐️ Absolutely Game‑Changing — Highly Recommend!

I’ve been using the BrainGain 16‑in‑1 Adjustable Dumbbell Set (40 kg / Pair) in my training routine and it has truly been a game changer. The quality and build are excellent — sturdy, well-made, and durable. Adjusting weights is smooth and quick, making it perfect for efficient workouts. The value is outstanding for such a versatile set.

I also had a minor technical issue recently, but it was resolved swiftly under the 2-year guarantee, with clear and helpful communication throughout. Special thanks to my advisor Sultan, who guided me through the process and ensured everything was sorted promptly. His support really enhanced the experience and shows the team’s dedication to customer satisfaction.

I’ve seen other positive reviews praising the build quality, versatility, and excellent value, and I can fully echo that. If you’re looking for a high-quality, space-saving dumbbell set, this is it!

Highly recommended — 5★ across the board!

Very nice piece of equipment. Feels good to hold and it is really easy to change the weights. I have been using it for a month now.

I needed some billing information change and was kindly supported by Bilal.
