Perfect for small apartment/beginner weight lifters.
Alright, dollars to donuts, this is an excellent deal.You get a barbell, two dumbells, one kettlebell and 50lbs of weights for about $110 CAD (I guess this product goes on sale pretty often, so your results may vary, but I got it on sale, and with a coupon)Regarding people complaining about the lock nuts coming loose; that happens with most weights honestly, especially if you're just beginning and your form isn't great (shaking, swaying while lifting). Sure, probably worse than full metal equipment, but unless you want to pay double the cost of this set, suck it up and just re-tighten as necessary. think of it as an additional forearm/grip workout.weights themselves are excellent quality, though a little greasy coming out of the box.ONLY reason I'm giving it a 4, is because you only get 1 kettle bell base, but 2 kettle bell grips. I mean heck, you might as well throw in the extra base yeah? To be clear, the ad states there's only one, but come on man.

I really like this Dumbbell set. It has nice feel to the texture.
And although plastic, (or perhaps vinyl), they don’t feel cheap.

The set looks good, too. I like the Orange and Black look, compared to the other Red and Black sets available.

I also really like that you can spin the orange locking nuts on by giving them a good hard spin - and they'll keep going - sometimes all the way on, (depending on how hard you initially spin them), without having to constantly keep turning and cracking them all the way on. (Same with removing them.)

The orange locking nuts have 2 opposing 'extended nubs' on them, to aid in cranking them down tight.

There is a foam-padded area on the center bar that would touch or rest on the back of your neck, when using the bar fully extended with both arms.

The two shorter individual threaded bars turn in quite far - all the way into the center bar for added stability.

There are also 2 Kettle Ball Handles, and a dedicated Kettle Ball End Piece, which helps me keep a controlled grip on them, when slowly and carefully using the weights to dip behind my back and shoulders, (among other alternate exercises).

The spacious openings of the Kettle Ball Handles are plenty wide enough, as well, (if two hands are required or preferred), allowing for different positions to hold, grasp, and maneuver them.

For a really good product, it’s very well priced, compared to the other options available.

I’m happy with the set!

[One Word of Caution: I would caution against dropping them, though, as they are most likely filled with sand, (or something similar), and could therefore crack and split open, if dropped from high enough up.
There is a bit of a slippery feel to them to be aware of.]

Each Dumbbell arrived individually protected in its own soft sleeve.

I recently purchased an amazing set of dumbbells and kettlebells with a connector from Amazon, and I must say, it's a game-changer for my fitness routine. The versatility of this set is unmatched, allowing me to switch between dumbbells and a kettlebell with ease, thanks to the innovative connector.
The weights arrived in pristine condition, boasting a sleek design and a clean finish that speaks volumes about their quality. Setting them up was a breeze; the easy-to-install feature made it possible to start my workout within minutes of unboxing.
What I love most about this set is the comfortable grip and the sturdy construction—it feels like they're built to last a lifetime. Whether I'm doing curls, squats, or kettlebell swings, these weights provide a stable and balanced experience, enhancing my workout efficiency.
The durability and aesthetic appeal make this free weight set a fantastic addition to my home gym. It's not just a purchase; it's an investment in my health and fitness journey. I highly recommend this set to anyone looking to elevate their workout with high-quality, adaptable free weights.

For the price I was surprised. Weights are exact ( had an issue with another brand ) but these are perfect. Good value considering the price I paid for my metal weights. I actually prefer these ones over the metal plates. I’d definitely buy again.

5.0 out of 5 stars Great Set!

This is a great set for my needs and I'm very happy with the product and price point. Quality of the set exceeded expectations and I like that there are many configuration options with the pieces. I was torn between this and the cement filled plastic 50lb version from the same company, but ultimately decided on this one as everything that matters is metal including the threads and fixed nuts (although 10 lbs less). The nuts can also be locked in place with the included hex screws and allen wrench; however, for my use the rubber friction lock rings on them are sufficient (still pay attention though as they do sometimes "walk" and need to be retightened). The coating on the weights themselves is a nice thick gray powder coat. I would definitely recommend this set to someone who needs this weight range whether it be for toning or a low impact workout.

I ordered these having wanted some weights in house to use when I can't get to the gym. They work great for making various different weights. I do wish I could buy the plates on their own to be able to increase options without having extra bars but I suppose that's not a huge deal.

No issue with swapping out configurations and they really don't take up that much space.
