Just tried these out a couple nights of play for a few hours. So far, the first two we've played with have performed well. They feel very similar to the white 3-star Nittaku 40+, but even slightly harder, and with a strong bounce. It might not be to everyone's liking but I give it high marks for playability and consistency. And depending on the lighting and table color, these provide very nice contrast and are easy to follow.
