"Had one that wouldn't fire correctly the bb's would hardly come out. Got another one thanks to the innovations company. This one actually worked but sadly I saw a few clear flaws with this grenade. The way the bb's are held inside losely means you're more likely to get bb's jammed which results in less bb flying out. The actual mechanics or design of the impact is genius and is the best part of this grenade. I would say if the company had transfer this design over to the Tornado it would be perfect. But sadly the two grenade now just sit in a corner. I would say wait for something better.
"Works very well and is fairly easy to reset. However taller grass renders these grenades almost inert and there is always a a few straggler bbs left in the grenade. The pre-order/launch edition can with 2 patches, both were PVC.
Not ear shatteringly loud, but you still know if it goes off near you.
Green gas powered.
Impact trigger doesn't always go off the way you expect.
Only works on hard flat surfaces. Don't even consider using this in the grass, ever.
Poor seal in the gas port.
I got this grenade a couple months ago, and I enjoy using it a lot. It has a few definite issues, but is fun. While it is not ear shattering like a Thunder B, you still know if it goes off near you. A lot of people say the pins and spoons are easy to lose, and this is true. However, I just tied a string to them and then put them in a pocket after use. I use the string so I can let them just hang for a minute if I am in a tight spot. Between those two things, I haven't lost either one yet.
Reloading takes a little time, but its worth it for the reuseability. Between each use, the instructions say to oil the gas cylinder, arm the trigger, fill the gas, load the BBs, and reassemble the grenade. If you are fast, this can take between 30 and 45 seconds. If you are like me, it takes between a 60 and 90 seconds. This is more difficult if you have shaky hands after an exhausting game, but isn't bad at all.
The only thing I really dislike about the grenade is the green gas port on the bottom. I don't know if I just got a bad seal in mine, but whenever I fill it, it leaks everywhere. This is an issue with how the gas can actually seals to the port, NOT a leak in the gas cylinder. So once it is filled, it stays full. Its just filling it is kind of a pain.
The real issue with this grenade is it limited functionality. It only works in specific situations and specific locations. You need to understand how the grenade works to see what the problems are. The impact trigger is armed by pushing a pin up to compress a spring, then locking the pin in place by tilting it to one side. If something moves the pin, the spring slams it down into the gas cylinder. The gas is then released into a single long tube that runs back and forth through the inside of the grenade (which you fill with BBs), and out a hole in the side. This causes the gas to propel the BBs out while violently spinning the grenade.
There are two problems with this setup. If the wrong side of the grenade hits a wall, it won't go off. I tend to put a spin on it when I throw it, so if it doesn't go off when it hits the wall, it goes off when it hits the floor. I have only used the grenade in a game a few times, but so far it has always gone off. The other issue is that it must be on a hard flat surface to really work. This will not work in grass at all. Especially if the grass cushions the impact and keeps the grenade from going off. If it does go off, the grass will block the BBs and slow the spin down a lot. This means the grenade is only really useful in developed areas like buildings and towns.
If it wasn't for the bad seal in the gas port, this would have gotten 5 stars. Other than that, it is exactly what I expected.
