Review on FLYBIRD Adjustable Dumbbell - Fast Adjust Weight, Anti-Slip Handle, Perfect For Full Body Workout by Bobby Diaz

I received these a few days ago and I really like them so far. First of all, the handles and the weights themselves are very comfortable. They fit my hands well and are easy to work with. I also like the weight-switching mechanism, it feels solid when it latches in, and it's easy to do with one hand.I have noticed that they feel slightly asymmetrical (along the rotational axis) when lifting them due to the shape of the weight plates, they have a very slight tendency to want to "roll" in your hands. But this effect is very minimal and and doesn't interfere with the basic functionality. For product improvements, my suggestion to the manufacturer would be to design each plate slightly "out of round" to compensate for the gap at the top of each plate. Either that, or mill them slightly thicker at the end where the gap is to compensate.High marks over all for quality manufacture, comfort in the hand and ease of use.Thanks
