Just received my junior aluminum roller the other day. First of all, it's very well made, smooth and silent, and the teal color is gorgeous! Unfortunately, even though I thought that 4 oz would be light enough, it really hurts my wrist to use it, even for a few seconds. To be fair, I'm a petite lady in my 60s, so maybe it wasn't the best choice for me. I'm hoping that I can find other ways to use it that aren't painful, since it really is beautiful.
