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.

These dumbbells are of good quality, exactly the type i wanted as these have a wide range of the weights and i can change them easily. The ease of adjustment and assembly is perfectly good. The value of money is perfect for these adjustable weights as they can be used for kettlebells and barbell also.

Very nice set! You get a lot of variations with just a few changes to the accessories. Really like the kettle bell option...those things are expensive. It's easy to change out "settings" to use them the way you need to. The grips are comfortable.

I’ve had these for at least a year now and they continue to hold up. The bars for the dumbbells are a little long, but other than that they are great.

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.

This set is ok but I can’t get enough weight on the kettle or bar because the plate increments are so WEIRD! The screw on system takes too much time to change the plates around. The company did not offer clip collars but I found some on Amazon that works great. This company needs to get collars and offer 10# plates to the set. Got 10# plates thru FITVIDS here - they work great Got clip collars also on amazon that work great. Without these added purchases- using this system has a lot of frustrations

Multiple different ways to use this set, and target different areas of the body. You cannot beat the price for the quality of the products and all of the different was to utilize the weights. From dumbbells, to utilizing the bar and bench pressing, anyone can get an effective workout in. Easy to store, due to the ability to break apart the pieces. It's the perfect size, and easy to assemble.

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!
