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!

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.

The weights are listed at 90 but only go up to 88 (unless the dumbbell piece is 1 lbs). Overall the set is pretty okay however the center piece to connect everything is very unstable and can easily break. For anyone looking to get an adjustable set these aren’t bad just don’t look forward to the barbell component lasting long. I’ve tried super gluing the pieces together after they slipped off however it just continued to slip off and or break from the pressure. Still not bad overall, would just recommend buying a legitimate barbell and weights with it. Grab a few dumbells too and stick with your investment. Godspeed

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 !

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.

Broke within 6 months with very minimal use. Not easy to use at all. Takes a long time to switch weights. Not worth the money. Spend the extra $40 - $100 to get quality ones that will last you years.
