Zestaw 12 skorup granatów dźwiękowych Thunder B Shocker [Hakkotsu]

Arrived within 7 days after ordering (to Portugal)

Compared to the flashbang style black model this one explodes much faster, around 2 seconds compared to the 4-5 on the other one. This is great if you play mainly CQB. The grenade rips open consistently on the white line as shown in the pictures.
The only downside is the lip that threads onto the grenade head is longer than the other models and you have to be careful not to over tighten it when assembling. I did this on my first try and it got stuck to the grenade top after exploding, and when detaching them the thread thats glued to the top part came out with the casing, permanently disabling the system. I had a spare thunder b system and I tested it without tightening too much, worked fine and there was no damage anymore, even though you have to be careful to slowly unthread both parts.

Bottom line, for the price it's probably the best choice for CQB players. No more cooking a grenade and hoping it doesn't go off in your hand.

Definitely the most reliable for the thunder B, gives a nice loud pop and haven't had any of these just shoot out air without bursting.

And the colour is nice if you actually use it out in nature as a tripwire as it'll blend in.
