I got this item for around 70, it’s an easy to assemble very fun to use product. Might even get a heavier set in the future but it’s a great tool to get back into shape or continue implementing fun workouts.
J. C. –
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.

Weight sets can be crazy expensive! Don’t waste your money on them when these are perfect for home and personal gym use!!! They are well constructed, super easy to assemble and disassemble. The size, grip and ergonomics are comfortable and well designed. This set exceeded my expectations in every way.
View and Chew –
Works as intended but remember you can’t increase it’s weight so remember that before you buy I use mine daily but in year might be time for me see if they sell ones with longer bars and more weights
Devon –
These are a great introductory set of weights for people just getting into bodybuilding or for those who just want to do strength training with an easy to use weight kit. It’s been a nice little set so far and really helpful on my fitness journey.
BoutiqueMama –
I read many reviews before purchasing to make sure these were sturdy, easy to use and a good value. I can check off each of these after I’ve been using them for a while. The instructions were easy to grasp right off and they’re a great part of my home gym. Only drawbacks 1) I’ll need to order another set to increase weight eventually and 2) Although the process of adding/subtracting plates to the dumbbell/barbell is simple, it’s not instant….you have to twist off the cap, then twist it back on….not hard, just takes a little time in between sets. But, that’s reflected in the low price I suppose.
Irene Glenn –
I bought this adjustable dumbbell set for my boyfriend so he can work out at home. The set is easy to adjust and he was even able to add a different set of weights to the bar. This set is very functional as it comes with two dumbbells and a barbell attachment. The one thing my boyfriend thought could be improved was the weight of the plates. The set comes with 4 plates that weigh 2.5 lbs and 4 plates that weigh 2 lbs which totals 18 lbs. I would recommend this specific set for beginners and the sets with more weight for people with more weight-lifting experience.

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.
Irene Glenn –
I purchased this product, I believe back in March of 2024, I have just recently unboxed the item on May 19, 2024. This is what I was looking for versatile and lightweight. Easy to move from one exercise to the next without difficulty of changing up the equipment. However, my disappointment comes in, is that the barbell is too short to rest on my weight bench which was the sole purpose of me purchasing this item. I don’t know if the reason it falls a bit short is that my connector does not look like the on pictures in the brochure/instructions. If that is not the case and I have the correct connector you may want to consider making the barbell a bit longer.

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.

Ian Fildes –
I have never written a review as quickly as I have today after receiving these weights.
Normally I like to use whatever product I purchase for a couple of weeks so that I can give an honest educated review.
With this product though, I don’t need a couple of weeks to know the quality of this set is awful. And it’s awful for a plethora of reasons. Here are the top 3 problems with this product and reasons you should NOT buy from this seller:
1. The dumbbells can be assembled, however, with every part of this product (aside from the weights themselves) being plastic, no matter how tight you think the nut is screwed in, it loosens within seconds of lifting them and the weights begin to move around thus making it difficult to remain in a steady position. So unless you are fine with continuously retightening the weights in place between each lift, the dumbbells are pretty well useless.
2. The kettle bell rods threading is completely off, so I can’t get the rod to twist into BOTH kettle bell handles without it getting completely stuck to the point where I couldn’t even twist it off on my own. So the kettle bell is also useless to me.
3. The barbell rod that connects the two dumbbells, also has a threading problem, so it will not twist in tight which means I can just pull it out without twisting it. Once you get to the middle where it should tighten up, it just keeps twisting. You can’t use it without the risk of the dumbbell slipping right off mid lift and severely hurting yourself. Again useless.
EDIT* Over and above those 3 things, the weights do not total a weight of 50lbs (which was what I thought I was purchasing). I was so busy paying attention to all the other issues with this set that it took 4 days to realize they don’t add up to 50lbs.
The weights add up to 19kg, which equals to 41lbs NOT 50lbs.
I ordered 50lbs, but I’m getting 41lbs???
MAKE IT MAKE SENSE SELLER!
So all in all I spent $125 on a completely versatile weight set that I cannot use.
The fact that this seller has listed this product for an outrageous price should be criminal, considering what I received today. I truly feel robbed of $125.
I knew this was plastic, however, with paying $125 on them I figured it would be (at the very least) half decent quality- not as bad as this. Very disappointing and very frustrating. Do not waste your time, energy and most of all, your hard earned money on this product.
Trust me when I say BUYER BEWARE.

I will add photos later. 4x 2.5 disks. 8x 5# disks This allows a number of different combinations up to a 50# barbell or 2x 25-30# dumbells. I haven’t tried the kettle ball yet but I think you could get 25# (5 disks It only takes a few seconds to piece together a full barbell. Transition should be pretty smooth to go between weights or dumbbell/barbell.
To be honest though, I should of bought the 70# or even the 90#. I typically can’t bench more than 50#, my arms are thin. this gives me a nice range to work up to another level. or at least stay toned. This might be good for a teenager who is new to working out. The investment is nominal and if I stop using it I won’t mind the cost and can donate it to charity later. If I step up to the next levels I will be able to have barbells and dumbbells’ together and a fuller set and have a smoother workout. There is no reason to scoff that these are plastic. They are most likely sand or a concrete under a polymer shell. They make it easier to handle and cheaper to make but without sacrificing quality. There is no real reason to have metal or lead for weights that make them more expensive. Thermo plastic is fine. I would not slam or drop these, but you don’t need to soft handle them either.
