Someone thought the heckler was a good idea. Likely several someones... it makes me wonder what the product development cycle looked like. What were you thinking, guys?? Thankfully, you CAN turn off the heckler. Trust me, you'll want to.
The board keeps score very well. It's great for 301/501 for those of us who have trouble with the instant math required. With the heckler turned off, the game calls out each hit in a cheerful voice. Much better! It's been flawless in it's accuracy in detecting hits correctly. Has "Bounce Out" feature to reverse out a dart hit that subsequently falls out or bounces out.
The board is easy enough to set up, but keep the manual safe, because the variants are not easily discernable without it.
It's been said elsewhere, and bears repeating: Do no bother to even assemble the set of darts that come in the box. Pitch them in the trash. They're unstable in flight. They're also too light, weighing in at 9 grams each and feel like you're throwing nothing. Without sufficient weight they don't stick well and are constantly bouncing out. Real darts weigh generally no less than 16 grams, and preferably 18 grams. Big difference.
Get a set or two of real darts. Brands like Laser, Bottelsen, Harrows, Dart World... Anything that's 80% or 90% Tungsten generally is a real step up. Tungsten darts are slimmer than brass for the equivalent weight, meaning in tight groups you don't have your prior dart crowding your next incoming dart out. Stay away from the cute "bumble bee" buzz bomb/torpedo style brass darts for that reason. And Tungsten darts have no lead content to worry about.
Another reviewer mentioned flights coming off. Yes, flights come off even the best of darts. They're supposed to do that if 2 darts come in close together, the incomming dart would cut/smash it's or the other dart's flights if they didn't. BUT... you can get spinner shafts like TopSpin that will help with that problem, allowing the flights of each dart to rotate out of the way of each other. If it keeps happening for no reason, suspect your shafts are the problem and not the dart itself. You can get different shafts for like $5 per set.
