This pucks center-weighted design means it's less apt to roll over on it's side during passing/skating play, but because the outside circumference of the puck is so light, you cannot create the spinning gyroscopic effect needed for slapshots, or any fast, hard shots in air. This puck refuses to whiz through the air for slapshots, rather it just tumbles end over end and bounces a lot when you hit it hard. Because it doesn't behave like a hockey puck, I recommend you stay away from this one and go with something more traditional. 2 stars

I have played roller hockey for 17 years and these are some of the best pucks, in my opinion. I feel they release off the blade of the stick better than 90% of the other pucks out there. Also, I have not had trouble with these pucks "fluttering" like the other reviewer did. They also slide really well. Most of the reasons I like these pucks are the reasons I'm sure most goalies hate them. They are quick and fun for the offense. An added bonus is that they aren't too expensive. There is only one puck I prefer more, but it is twice as much. 4 stars

Maybe someone doesn't know how to take a slapshot. I have used these pucks for over ten years and have not ever had a problem with them fluttering. These IDS pucks are the closest thing to ice hockey pucks. I do think the price here is way to high though. The pucks handle great and because of the weight they tend to glide across concrete and sport court surfaces without jumping up on edge. 4 stars
