Better than expected I am a little concerned with the plastic nuts and if they’re going to break or not eventually It is kind of a shame that the pool stick out when you don’t have a lot of weight on them and you can just hit yourself with them But these are like high-quality and awesome and I am just so happy and wish I had ordered them years ago

Easy to use, a little tedious to reconfigure every time you want to change handles, but I’m not in a rush when I workout anyway. Weights are easy to adjust, versatile for exercise plans, comfortable in the hand, and feel like good quality. Overall worth the money!

Just opened it, everything seems to be included and intact ( I have to double check because I just skimmed over everything). I haven't tried it out as yet but I'll update on that as soon as I do. Quality seems pretty good for it not being full metal. Only thing I did not like was the box was falling apart from the weights but other than that I'm pleased that my order came as advertised. I can't afford a gym membership so why not start with something affordable that I can use at home. I'll be sure to get back on how it turns out after using it.

Quality is fine, all plastic, and I think the weights are just sand or something similar but just fine for a home gym. It is a bit annoying to have to unscrew everything when switching up workouts but that's just how they work. I think for the price they are great.

They get the job done... But... I bought these to replace some adjustable weights that I had to leave when I moved, but these are just not the same... I appreciate that these have a bar & kettle bell option, which is why I got them, but I just can't justify spending minutes between every set adjusting the weight. The ones I had previously, you could literally twist them and adjust the weight with a click. These, obviously, you need to take the plates off and put new ones on every time you want to adjust the weight. Not to mention, some weights just aren't possible with the available plates. Of course, I knew that this would be the case when buying them, I just didn't realize how annoying I would find it to adjust the weights all the time. I already don't have oodles of time to workout, so having to sit there and figure out which plates I would need, and having to try and minimize the amount of weight changes I would need to do during the workout... It's just not worth it for me. If you are in no rush / don't really care about this at all, then yeah, these are fine. But if you are already in a time crunch with workouts, maybe look for ones that are easier to adjust... Pros: - The bar & kettle bell option are really nice - Nice grips, comfortable - Comes with little weight-lifting gloves Cons: - You spend a lot of them adjusting the weight between sets - Takes up a lot of room - The fact that you need to stack up plates to reach a certain weight makes it sometimes awkward to hold/position because the dumbbell needs to be so wide (but this is true for pretty much all adjustable weights) TLDR; If you don't mind having to take off + put on plates between sets to adjust the weight, then these are a fine option. If you already have a short time to work out, look for different adjustable weights.

I really wanted to like this set because the concept is great—a single product that can be used as dumbbells, a barbell, and kettlebells. Unfortunately, it didn’t perform well in actual use. As dumbbells, they don’t feel very comfortable or balanced. When converted into a barbell, the weight plates don’t feel securely held in place, and there is noticeable movement and wobbling during exercises. The biggest disappointment was the kettlebell configuration. The weights are held together with a small plastic screw/locking mechanism, which doesn’t inspire confidence. Even when tightened, the kettlebell still feels loose and wobbly, making it uncomfortable and distracting to use. If you’re lifting very light weights, it may be acceptable, but I wouldn’t recommend it for anyone looking for a solid, stable, and confidence-inspiring workout. I ended up returning it because I didn’t feel safe or satisfied using it. The idea is excellent, but the execution and build quality need significant improvement

This product is pretty cool and it’s extremely versatile. If you don’t want a bunch of separate weight products taking space this definitely helps. I say it’s worth the money ! And easy to adjust weights !
