Reddit reviews Franklin Sports Street Hockey Puck - NHL - Colors May Vary

I've been using some pretty cheap franklin street hockey pucks, picked one up at a 5 dollars-or-less store, for 2.99, and its lighter than an actual puck and about the weight of a ball. It just doesn't glide nearly as well as anything, and honestly when it comes to street hockey I'd rather just use a ball.

But you didn't seem too concerned about the actual puck, as much as someone getting hurt. And for 3 dollars I think you can accept at least trying it out. It's 6.99 here but I'm definitely sure you can find it somewhere else.
