I bought these from Woot a little over a year ago (without the stand) and I love them for the most part.
Very sturdy, easy/quick to switch out the weight, and supposedly retain their value pretty well.
My only complaint is that there are some things (overhead tricep extensions, for example) that are a bit harder due to the blocky shape and four bars that surround the central bar. I can still do them, but the corners like to dig into my palms when I do.
I bought the 70 lbs. set a while ago, and was about to buy the stand today. Unfortunately, this is the small stand that is only rated to hold the 50 lbs. set. Makes sense since that’s the set on sale today, but it doesn’t work for me.
