"I was excited to finally get some of these but the first time i actually got to field this it broke. The pin holding in the spoon broke so i had to find the spoon. After fixing it i had a bunch of duds and finally today 1/5/15 i decided to fix the pin for the spoon again but the threads inside the thunder b head seemed to have cracked so now the head of the thunder b wont even stay on.

Pros: good for clearing rooms. Loud. Have a bunch of different shells you can choose from.

Cons: cheap build quality, the plastic threads break.

Maybe i just got a defect. Try it out for yourself its super fun when it actually works.

"These are incredible!

Having used every Thunder-B shell type, these are the only shell type that give reliable detonation every single time.

These grenades are fantastic. They put out about 120-130 decibels. These are definitely louder than a firecracker. Anybody that it goes off near will DEFINITELY call out, if not be disabled long enough for you to shoot them. There are no doubts that this grenade is just as loud as you could want it to be.

Assembly, disassembly, maintenance, and preparation is pretty quick and simple.
Very durable (though the metal bends sometimes after rough falls, so you have to bend it back)

Head assembly:
~Firing pin head
~Firing pin point
~Safety Pin
~Black metal sub-connector
Cylinder assembly:
~Aluminum cylinder
~Aluminum bottom cap (with rubber stopper)
Disposable shell

Pull the hammer back and use the spoon to hold the hammer back. Insert the pin into the head to hold the spoon (and thus hammer) in place. Screw the black metal sub-connector into the bottom of the head.
Loosely screw the aluminum bottom cap onto the aluminum cylinder.
Insert a 12g CO2 cartridge into the Aluminum cylinder.
Screw the cylinder assembly into the bottom of the black metal sub-connector (attaching it to the head).
Once the sylinder assembly is tightly screwed in, start to screw in the aluminum bottom cap. You will notice that the firing pin head is slowly raising toward the safety pin (which blocks the hammer's path). Stop tightening the bottom cap when the firing head reaches the safety pin.
TIGHYLY screw on the disposable shell.

For the most part, if everything is tightened well and the disruption shells are being used, these will work every time. No reliability issues at all.

These are VERY satisfying.

"I bought the first generation Thunder-B and had mixed results. It was notoriously unreliable and many times the shells did not blow. These third generation shells are much better and I have not had any failures. My only negative critique is, these MUST be rolled or thrown on to a soft surface or else, you risk damaging the firing mechanism and spoon. If you want a big boom and reliable detonation, get these. I threw one in to the men's room at my station (police) and all the guys in there thought I was really, really cool.
