I purchased a set of Weider 35 lb. Hex Dumbbells more than a decade ago and they're still going strong. I was initially going to return these dumbbells after I weighed them and found out they were off by about a pound each, but after further investigation all of the Weider Hex Dumbbells at my sporting goods store varied in weight. The handles were really grippy initially and it caused a lot of blisters, but as time went on they became smoother. I have to grip the weight a little harder now, but luckily it doesn't cause any forearm pain and I don't get blisters. These dumbbells have withstood countless drops and still remain in tact. The smooth light gray finish wears away very quickly to reveal a darker gray that actually looks better, but it leaves the weights exposed to rusting. There is some slight rusting that has occurred over the years, but the weight remains the same. I would definitely recommend Weider Hex Dumbbells because they are durable, close in weight, cheapest by the pound, and stack very easily on top of one another for easy storage.
