I’m enjoying it!

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 ! Read more

Wish the locking mechanism was better.

CustomerMarch 11, 2026✓ Verified purchase

Other than the nut locking the plates in place loosening up every so often the dumbell set it great for me workout. I just wish the nut wouldn't loosen up so easily. It's not the end of the world, as I retighten between sets but it could be better for sure. I primarily use this for barbell workouts. Read more

Takes forever to change the weight...

HeatherJune 8, 2025✓ Verified purchase

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. Read more

Unsafe Product

Teshome bayeJuly 7, 2025✓ Verified purchase

I am writing to formally express my disappointment and concern regarding a recent purchase. After opening the product and disposing of all the packaging, I attempted to use it the following day. Unfortunately, I discovered that the product was torn and damaged, with parts loosely rattling inside. After just one use, the connector of the barbell broke, which is completely unacceptable and unsafe. I have attached photos for your reference. This experience has raised serious safety concerns, and I believe the product is defective and not fit for use. I contacted your customer service team immediately after the incident. I was told that the seller would reach out within 24-48 hours, but I have not received any communication for over five days. When I followed up, I was informed that I need to purchase a new box and return the item, which I find unreasonable given the circumstances. Read more

Easy Workouts!

IanSeptember 29, 2025✓ Verified purchase

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! Read more
