Save your valuable time and energy and just buy these. There are Strength Co. plates and then there is everything else. These are the best plates and it's not close. I have over 500lbs of these American-made iron weight plates, and they've been with me on my entire strength journey. No matter what happens in your busy life, stressful job, or kid's schedule, these plates are always there, always look good, always able to make you stronger than you were before. No joke, every time someone visits my gym they pick up one of these plates and are shocked at how good they look and how great they feel. As a busy dad trying to support a family, I want things I can buy once and they last forever and require no thought ever again. These plates do that. A valuable piece in my home gym that will forever be a staple. God bless Grant and The Strength Co. for making these and supporting strength and AMERICA.
