I bought the 41,5 kg adjustable dumbells and am very satisfied. I also had a little issue with a defektive part which was handled very fast. I was sent a replacement part and was very happy with Sultan who handled my request.

Jon was very helpful and kept in contact to make sure all was good with our treadmill. Even kept in touch afterwards to check if we need any further help.

I would not hesitate to order from this company again.

I recently purchased a pair of adjustable dumbbells from Braingains and I couldn’t be happier with my choice. The quality is absolutely top-tier — the finish and overall build are excellent, especially considering the price. In my opinion, they offer the best value for money on the market for this level of product finishing.

I’ve been using them consistently and I’m really enjoying my workouts with them. They feel solid, well-balanced, and durable.

I also want to highlight the outstanding customer service. I spoke with a team member named Sultan, who was incredibly kind and helpful. One of my packages was lost during shipping, but they immediately arranged to resend it without any hassle. The issue was handled quickly and professionally.

I highly recommend Braingains products to everyone — great quality, great value, and excellent customer support.

After an initial blip, my experience has been very positive. Four days after ordering a pair of adjustable dumbbells I hadn’t received a notification of dispatch and they had not been delivered. I got in touch with customer services for an update. Zain dealt with my email quickly and the dumbbells were delivered the next day. They are a solid bit of kit, weight change is very smooth and quick. Mistakes happen, there was an issue with their system, they fixed it quickly and were transparent about it. Thats all you can ask for. Great service and great product, especially when you compare the price to other brands.

We ordered adjustable dumbbells from Braingain. Initially I was sceptical about the quality, the 24KG pair looks good and hope we will be able to use it for long term with regards to quality.

Sultan from Braingain team was very supportive in resolving our concern with the purchase of adjustable dumbbells and the process was very smooth. Thanks!

Had an issue with my dumbbell and they promptly issued a replacement as well as good and fast customer service during the mail contacts with the service member Sultan.

Amazing set of adjustable dumbbell of 40kg each! Very happy with it

Delivery on Point with UPS, and first impression and training with the 2 Braingain 41.5 kg was very good. I hope they will last many years.

I’ve been using the BrainGain adjustable dumbbells for a while now, and I can honestly say they’ve exceeded my expectations in every way. The build quality is outstanding — solid, well-balanced, and clearly designed for long-term use. The adjustment mechanism is smooth and intuitive, making it incredibly easy to switch weights mid-workout without breaking momentum.
I also appreciate the attention to detail — from the stability when resting on the floor to the satisfying, precise locking system. It gives confidence that the weights are safe and reliable during every exercise.

The adjustable dumbbells (41.5 kg) are a real game changer for training at home. The build quality is excellent, everything feels solid, and the adjustment mechanism works smoothly.
Delivery was quick and hassle-free, and the secure packaging with thick Styrofoam molds left nothing to be desired. Overall, an excellent experience; highly recommended!

I purchased the 24kg dumbbell which are prefect!! No issues and they were very good with communication

Good quality

After an initial wobbly start with brain gain I have to come and ammend my review. While delivery took longer than expected and comms related to this delay were poor, the item itself (walking pad) arrived and it's good quality and study. Then post sale I was contacted by the customer service team to apologize and try and make ammends which I can very happily say they have indeed gone above and beyond to rectify this small error. We can all make mistakes, it's how it's delt with that shows how good a company is and brain gain really did get there in the end. Many thanks to Molly for her aftercare, it's been exceptional

MY RECOMMENDATION: DO NOT ORDER.I booked express shipping (“1–2 business days”), but in the end the delivery was significantly delayed and incomplete. Only the dumbbell stand was delivered; the dumbbells are still missing. At the same time, the Shop app showed the order as “delivered” even though not everything arrived. I only received the express shipping fee refund after complaining, but that’s not the main issue. Overall very disappointing: shipping handling, status/tracking, and communication do not meet expectations.

MEINE EMPFEHLUNG: NICHT BESTELLEN. Ich habe Expressversand „1–2 Werktage“ gebucht, am Ende war die Lieferung deutlich verspätet und unvollständig. Es wurde nur der Hantelständer geliefert, die Hanteln fehlen weiterhin. Gleichzeitig wurde in der Shop-App „delivered“ angezeigt, obwohl nicht alles angekommen ist. Den Express-Aufpreis gab es erst nach Beschwerde zurück, aber das ist nicht das Hauptproblem. Insgesamt sehr enttäuschend: Lieferabwicklung, Status/Tracking und Kommunikation passen nicht.

I received mu dumbells, there was a problem with one of the weights (instead of 2.5 it was a 1.25 kg) which was swiftly handled by the support staff. The workout is well-fitted to my needs. Great product and I commend the support staff! Keep up the good work!

Bought 36kg pair of adjustable Dumbbells. Delivery very quick. Packaging secure over three boxes which made getting them in the house easier. Assembly straightforward. So far they work suberbly and I love them. Using alongside the Gym to allow me to sneak in lots of extra lifts through the day. Only used weight ranges from 8kg-26kg so far so plenty of room to grow. Definitely recommend.

I recently purchased a set and they have been an absolute game changer, in just a few weeks. Getting to the gym has always been tricky due to time constraints. But at home I don't have the space to have loads of kit. Braingain have provided the perfect solution! These dumbells offer exactly what I need and they tuck away neatly. Plus the ability to shift between different wrights is so smooth. Very impressed.

I’ve ordered 2 x sets of dumbbells from Braingain and I am absolutely delighted with the quality of the product. The customer service was excellent even when there was a slight issue on delivery this was rectified immediately. I’d 100% recommend this company

Such a great service! The dumbbells are great and if there is an issue they will help fast and with a proper solution. Thanks guys :)
