First off, I'm reviewing for the #sweepstakes otherwise I wouldn't leave a review at all - and that's a good thing, because that these things work as advertised! They're dumbbells that you can adjust and they effectively replace a whole host of expensive and bulky dumbbells. That's what they do, and they do it well: simple, really. In these days of a rapidly declining economy (after Jan 2021, hmmm...), I found these to be a better investment than a full weight set for the time being, and far better than a gym membership contract (prepping to move so I can't commit). These fit the bill, even though I believe them to be a tad expensive for what they are. TL;DR: They do what they should as adjustable dumbbells and may be worth the cost (hence, 4/5 stars). YMMV.
This is a great alternative to having tons of weights laying around. Super easy to adjust weights during sets too. Recommend the stand that goes with it as it's the perfect height so you're not constantly bending over.
Pros: Comfortable, Durable, Easy Storage, Easy To Set Up, Easy To Use, Strengthens
