I bought this and the Irwin version at the same time for about the same price. I don't know why Irwin suddenly skyrocketed because it's bullshit and broke almost immediately. This one still holds. The only thing I generally dislike about the nature of this type of clamp is that it doesn't actually connect the boards together. Basically you need a separate clip to tighten them and then this one to keep them straight. Although it works fine for this purpose.
