APS Thunder B Airsoft CO2 Simulation Grenade (Model: Tripwire / Set of 12)

"So, I bought these and used them in the summer, and they are great!! Extremely loud, especially inside, people WILL duck. Still very loud outside, of course the harder the surface, the louder the bang (if it blow in grass and the rupture is on the bottom, sound can be muffled). Only 1 con. This is C02. I used them in a outdoor event in the winter (24 degrees with light snow on ground) and the way this is designed, the C02 fills the grenade and bursts for effect. C02 is VERY SLOW in cold, and instead of a 5 second delay from activation, it could take from 30 seconds till never, since the pressure took so long, it may not blow up the shell.

Great for regular weather!!!
SUCKS in cold.

Still recommend.

"Not a bad option for people wanting to get into airsoft grenades at an affordable price. HOWEVER, if you use grenades regularly you may have more headaches with this system than others. The low price shows itself when I cannot get one of these cores to last more than 10 detonations on average. The metal used is just too poor quality to withstand the pressures and force exerted on the system. I've had spoons break off, and threads strip from detonation. If your field allows I suggest looking into blank-firing grenades if you want a high-quality reusable airsoft grenade. Build quality and durability are superior with those, but the only downside is if your field is prone to thieves then the Thunder B might be the better option.

"These are a bit of a crap-shoot to use. When they work, they work great, but when they don't, you just stare are a shell for 30 seconds wondering why it failed to fire this time. The core seems to be almost schizophrenic about which CO2 carts it wants to use, we discovered crossman's are the most likely to fail, but uKeg CO2 cans are about 90% effective. Maybe the piston on ours is underpowered and still passed QC, maybe Crossman is overbuilding CO2 carts, but all in all it made us prefer the Bang 22 by AI in almost every single way

"Great product that can scare the crap out of you if your not paying attention. I give this 3 stars because mine broke on the third time. The plastic piece that holds the spoon on broke off so I cannot use anymore

"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.

"Bought these for my son. Not overly impressed. They explode only about half the time, but they are FUN when they do! We found that if we lightly score the outside they have a better chance of exploding.

"These are loud. Yes, the shell ruptures... that's what causes the noise. I can throw these 40 to 50 yards and the timing is perfect. They go off almost immediately after hitting the ground. Should probably "cook it" for a couple of seconds before tossing through a portal.

Cons: The pineapple shell is way too large to fit into a frag grenade pouch.

"Do the Shells break after one use? Because if not this would be a definate buy for me and my friends to use during our neiborhood games.

"I just got one of these and tried to use it yesterday. It took 4 tries to get it to go off the first time The second time, I dropped it with the pin still in and then picked it up and it went off in my hand. Luckily, I'm ok. Yes they're cheap and they're reasonably loud, but don't trust them.

"Bought it, used it, broke. Got replacement, used it, broke. Used my buddy's new one, and it broke. I swear, these are made of the cheapest metals around and just destroy themselves after one use.
