Flimsy, Dangerous, and Terrible Customer Service
I bought these because they were well rated on Wirecutter, whose opinions I generally respect. For the first 2-3 months of use, I really enjoyed them. They were priced decently, and extremely easy and convenient to use. I particularly liked that you only needed to twist the dumbbell handle in order to adjust the weight, rather than having to adjust a dial like you do on some other brands. Unfortunately, the quality of these dumbbells was not up to par. The mechanism and gears on the handle that actually grab onto and adjust the weights are attached with glue(!)Within 3 months of light use, the gears on one of the dumbbell handles fell off entirely, along with the weights that were attached. I had never dropped these weights, so I know I did not damage them. The gears simply detached because the glue that bound them deteriorated. I thankfully was not injured, but I could have been if I was performing a press in which the weights were above my head. I was astonished that the product quality was that flimsy, but I thought perhaps it was a fluke because the dumbbells are so well reviewed. And thankfully, because these dumbbells apparently come with a 2 year warranty for parts, I called Core Fitness to request a replacement handle.That is when I learned (as other reviewers have reported) that Core Fitness has virtually non-existent customer service supporting its supposed parts warranty. I spent 4 days on the phone waiting for several hours each time to try and reach a Core Fitness representative. None of my messages were returned. When I finally was able to get in touch with someone, they asked me to send a copy of my Amazon invoice to their customer service email as proof of purchase, and promised I would receive a replacement handle. I did so immediately, but never received a confirmation. I have tried to be patient and understanding in light of the Covid-19 pandemic, but nine months has now passed since I first tried to contact Core Fitness, and despite multiple attempts to contact them, I have not once received a response.In my frustration, I turned to the Amazon reviews to see if anyone else has had this problem and how they have solved it, and was shocked to see a number of 1 star reviews reporting my exact same problem: their handle was attached with glue, the glue failed after a few months of light use, and they could not get in contact with Core Fitness for a refund or replacement. I have never written a review before, but this made me realize that I needed to: These dumbbells are of dangerously poor quality and the warranty is effectively a sham because Core Fitness will not respond to any customer service requests. Do not purchase.

Great Adjustable Dumbbell Weight Set!
I never do anything half-*ssed regarding significant purchases, i.e., I research professional reviews and also get a take for personal reviews, especially the negative ones. Essentially, I gather my information and determine what is and what isn’t important. Same deal with these weights . . . So, this is what I determined about what was really important to me: 1. All parts were sturdy and well made/constructed; 2. Similar to number 1, that the weights had zero to minimum movement while working out; 3. The weight set was “compact” even when using maximum load of 50lbs; and, 4. The company supported their product with excellent customer service (note: I do not know this personally, but from what I have read, they do a good job of this).All of the aforementioned were answered positively by what I read and reviewed. So, what was my first impression? The delivery was on time and the packaging was excellent. Two boxes were delivered to my door, and I had zero issues with the boxes/packaging. Assembly was simple. Fast forward to working out everyday (upper body one day and lower body the next) the last few weeks and I am extremely impressed with my weight set. Why? First and foremost, I discovered for myself what others had already discovered – this is a quality weight set, with little to no movement of the weights while in motion; and the set is compact, where someone lean like myself can easily maneuver the weights while doing various exercises. For example, when you are doing overhead tricep extensions with one weight at maximum weight (50 lbs), it is very important that you have a good two handed grip while maneuvering into the overhead position. I was concerned before buying the weights that the adjustable mechanism would interfere or not be comfortable either during the process of getting into the position or actually doing the tricep extension exercise. NO WORRIES . . . IT IS QUITE COMFORTABLE – BOTH GETTING INTO THE POSITION AND DOING THE ACTUAL EXERCISE. Regarding the actual adjustment mechanism, it is well made and so simple to use. One turn of the wrist and you move the weight dial up or down. Simple.The only issue – a minor one – is removing the weights from the floor rack when you exceed approximately 25 or more lbs. This is simply rectified by using your foot on the side bar of the rack. Quite frankly, more times than not, it never happens if you remove the weights in a firm and deliberate manner.Conclusion? I am quite impressed with this adjustable weight set. Price was outstanding, as I only paid $249.91 and I am fairly confident that this weight set will last the rest of my life due to the quality of materials used to make this set.

Best set of dumbbells money can buy. They are very intelligently designed, perfectly balanced and can be used by anyone. 10/10 recommendation for this product.

We’ve been using these dumbells in our home gym for 6 months and we’re super impressed. The weights are easy to select/change and are sturdy out of the base station. What’s really assuring about them is that the weights slide into V-shaped slats. So when I’m on a bench and the weights are over my head its re-assuring to see that they’re secured by more than just the locking pin. “IF” there were ever a failure the weight likely wouldn’t fall on me…because the V-shaped groove wouldn’t allow it.The weights have remained locked during ‘fast’ (snap type) exercises and the handgrips have a moderate texture that provides grips without being as aggressive as knurling.
