The Weider Tech Powerswitch dumbbells and stand are very sturdy and easy to use. Assembly is simple- you just put a few screws in to assemble the stand and the weights come ready to go. The grip is really nice- is mostly metal but has a small oval section of rubber that your palm contacts which I think makes holding them very comfortable. Switching between weights is a piece of cake. The only system that I’ve found that is easier to switch is the Powerblock adjustable dumbbell set. To switch weights you pull up on a spring-loaded bar and slide that bar to the desired weight. The mechanics are smooth and there really is no way for the weights to fall out after the pin has been adjusted. Some reviews have said that the switching mechanism catches. I have only experienced that when I’m in hurry and don’t try to be smooth with the transition. Size wise the Weider Powerswitch 100 set is about as big as a hex 45 pound dumbbell, and I’ve only noticed a limitation in range in motion when doing crouched curls. They suit every other dumbbell exercise that I’ve done. 100 pounds is the heaviest they go, which limits some back and leg exercises, but that’s not a big deal for the types of workouts most people do at home, especially with adjustable dumbbells. Overall Weider has put out a great product for a home gym for a reasonable price, and I would definitely recommend to buy Weider Powerswitch dumbbells as an addition to your home gym, and would recommend them over other brands such as the Bowflex SelecTech Dumbbells, and the Lifecore Dumbbells. The only adjustable dumbbell set that I might recommend over the Weider Powerswitch is the Powerblock set.
