The weights are beautifully finished and slide with just the right amount of friction onto the bars. The quick release collars hold the weights firmly in place and are easy to put on and off. Haven’t tried the collars for the seventy pound dumbbells yet but given their attention to detail I expect them to work well. Definitely would recommend to friends and would buy again
USA-Iron provided timely updates when they were backordered and then delivered as promised. When the product arrived damaged during shipping, USA-Iron provided immediate support and ultimately solved the issue at hand. I've had the dumbbells for about a month and have been very happy with my purchase. Switching plates with the quick change collars is fast and simple. Weights do what they were designed to do. Definitely would buy from USA-Iron again.
