These darts are something else. I've thrown many different kinda of darts from all different manufacturers and these are the only ones that have been consistent for me. I've had them for 3 years now and thrown countless games and they just keep trucking along. Perfect weight distribution, slim, tough as nails, great positive grip without being overly grippy...just a fantastic product. I've replaced the hammer head tips because the internal parts broke after a few months of play but that's to be expected. I would order replacement tips when buying these darts. I've changed everything about them except the barrel many many times and the threads hold up great. These darts took my game from decent to very good in a very short time.The tip seemed like a great idea, but in the past couple of weeks of throwing I've still seen so many bounce outs. Really... if your concern in bounce outs, get and maintain a good board that uses slim blades. The grip is great, the shaft is 1.5 inches, the tip is gimmicky and doesn't realistically work.This ad also mentions spinner shafts. There weren't any spinner shafts. I haven't been able to get a hold of Amazon LLC to corrrect this because you can't reach out to them. The only way to correct this is to setup a return and order another set of darts. This wouldn't be so bad if I was in the States, but I'm currently in Afghanistan. It takes 2-3 weeks to get things out here and 2 weeks to mail back. The quality of the barrel is ok but I could have spent a lot less for the same quality or slightly less.Have only had these darts for a little while but can already tell that you get what you pay for. These have an awesome feel and hit the board nice.Without a doubt the best darts I've ever had!Weight and balance are perfect. The darts never bounce off of the board and makes a nice "thud" sound when it hits bull.Darts look and feel great in your hand. The dart is not going to make you a better player, but you will look cooler losinggood darts!Great Darts
