APS Thunder Devil CO2 Single Use BB Grenade Shell (Package: Set of 12 with Core)

"I don't think you can beat these in terms of features, safety, price, and reliability. It really checks all the boxes.

I've thrown about 20 of these. Got multiple kills with most of them. Only one of them failed (leaked, I think it was a messed up thread). And they are just really cool.

"haha, grenade go boom.

(easy install, use and disposal. highly recommend)

"These are great.
Get the right shells, they aren't all the same.

"Great product for the price. Overall satisfying, I would definitely recommend these.

A couple of notes:

1. The shell must be tightened to the core very well to ensure the CO2 does not escape the shell, essentially creating a dud on the field (not a fun feeling). If you feel you have overtightened it, then you probably have it where it needs to be.

2. Fill to the same place every time. Recommended 140 BBs works great , but I use 200-220 BBs, which still gives about 3 seconds to detonation. Filling consistently ensures that you get comfortable with the time it takes the grenade to detonate without any mishaps. If shell is filled halfway or more, you will have to throw the grenade VERY fast to avoid self tags on the field.

3. For best effectiveness, ensure the white seam is either facing the ground or the sky after it is thrown. To do this, just tighten the shell and core so that when you rest the whole grenade on its side the seam will only face up or down (alternately, just make the seam and the spoon form a 90 degree angle to each other). Any other position will yield inconsistent or disappointing results.

"OK...first...

These things are great. Quality is way better now than it was a few years ago.

Now...be careful how you purchase these because even though Evike shows a discounted price for buying 12 shells plus a core for $28 reduced from $36 you can buy them individually for $26!!! The core's regular price is $20 and 12 Thunder Devils shells are $16.

Not really sure what Evike is thinking on this one.

SKIP THE SALE AND SAVE MONEY AT REGULAR PRICE.

"These dont fire super quickly like everyone says they do. Thats because people put waaay to many BB's in them. I keep seeing reviews that say "filled it half way and it almost exploded in my hand". 150 BBS is recommended and when you do this you get a good 3-4 second fuse. Pack the thing half way (alot more than 150) if you want a 1-2 second fuse. Anyways these are pretty much the best reusable BB throwing grenade out there. Super reliable and effective.

"PLEASE READ!

First off, these are great in the sense that they detonate consistently, and they also expel bbs consistently. Of course this is exactly what this shell was made for so I wouldn’t expect anything less. The only issue I have with these is that they detonate FAST, and by fast I mean fast. We tested them at my local field and we were averaging 1-1.5 seconds. That’s insane compared to the traditional Thunder B shell which usually takes around 4-5 seconds. This is caused by the smaller shell size, and I cannot stress enough how much you need to understand this before buying these. You may think 1.5 seconds is plenty of time, and it is for CQB, but in the field? Forget it. The first time I used one of these I nearly friendly fired my entire team because it detonated mid air. These are good for clearing rooms, or being tossed through windows that’s your covered on. As for open field throws, I’d steer clear of these otherwise you risk killing your self and your team depending on what your fields kill radius for grenades is (mines 20 feet, and it’s a struggle to get these 20 feet away in open field before it detonates.) Overall these are great, just understand that the fuse time is like a fourth of what you’re probably used to with Hakotsu. I just wish Evike posted the average detonation time.

"I like them and they are loud even out in the open, however the shells that come with these blow quick like 1 1/2 seconds maybe 2 seconds constantly! So please please please DO NOT COOK THESE! The thunder B shells take around 4 to 5 seconds consistently, or mine does anyway. I would use these in a situation where you do not have to throw these a ways away as it will go off quickly. Other than that they are amazing and I love them I highly recommend them.

"Smaller form factor than the Flashbang style shells
More reliable detonation than either the flashbang or larger cylinder style (mileage may very)

"I have used the core over and over and over again, several times in battle and it has never failed me. Metal spoon, loud af, and comfortable to hold. Easy to reload on the go.

The best and first purchase I've ever made when it comes to airsoft grenades. Make sure you only use the Hakkotsu cores. Extremely reliable. I haven't had a single issue yet!

"After much research on the perfect bb warrior grenade, I ordered the 12 shells with core, all came in one giant plastic package.

There were no paper instructions included in the box. This wasn't an issue, as APS has a YouTube video that is step-by-step. (go to youtube, search "Thunder Devil APS", watch the instructional video).

I have several types of airsoft grenades (EG67, Cyclone, T238 Nerf, Thunder Bs), and this is by far the best in my opinion:

+Very Loud (cuts down on not called hits, "i didn't know you threw one")
+Huge BB Payload dispersal (all bbs fly far and fast )
+Value (get 12 grenades plus core and co2 for $40)
+Reusable (as in the core, the co2 and shell and bbs are lost on payload deployment).
+FAST (3 seconds from spoon popping to booming)
++++BONUS: comfortably fits in 40mm pouches. AS IN PERFECTLY, as if they were designed that way. Good job APS! the only grenade I've used that I consider "worth it".

My 2 cyclones rarely go off (dirt too soft, hammer didn't strike, etc). EG67s are awesome and disposable but way too expensive over time. T238 is pretty neat but a bit of a dud, no sound and bbs barely travel a few feet.

Hands down: you want a grenade that LOUDLY announces its presence and spews hate all over the field for a few dollars a throw, this is IT!

"These are awesome best grenades I've ever used!!! BBs go everywhere!! VERY RELIABLE

"As a frag these are extremely effective and reliable. I have used three shells so far and all went spliting down the white line in on the shell. These are extremely loud and have a 3 to 4 second timer on them with both timing washers and a 2 second timer with only one timing washer. I recommend wearing hearing protection when these are in use because they will leave your ears ringing. I have had 100 precent reliability with these so far and already got my money's worth aster I scored a 15 man kill with one grenade (the rules at my cqb field use a room clearing effect based on sound but the bbs hit most of the occupants of the room too). When one of these land near someones feet they have no time to escape the instant they see it explodes.

The only downside is that the threads split (the white weak part on the shell extends along the threads too) every time as when the grenade burst making removal a pain as the shell is mostly a mangled mess afterwards too.

"These things pop bbs out and sound amazing. You will hear it across the playing fiels. They are insane in a good way. Great buy

"These are now the best and cheapest funtional frag grenades available in airsoft.
I was not optimistic about them actually shooting the bb's out.
Tested 2 shells. Keep in mind my cores have a hole drilled in it to blow earlier.
Filled one completely with bb's 200-300
I pull the pin and throw them while still holding the spoon. This blew up almost instantly about 2' from my hand and never reached the floor. Bb's went everywhere, none were left in the grenade
Second one i filled 1/2 way 100-150 bb's
This one made it to the floor and blew in 3sec.
Bb's flew everywhere and none remained in the shell.
