"Ok so i got this about 2 weeks ago and have played with it twice now. first time i played with it i played at mr paintball in Escondido CA. A large outdoor field with very soft ground. It worked but not that well due to the soft ground this is an impact grenade and likes something hard to hit for it to detonate. Now last weekend i played at camp Pen and this field has a ton of hard cover and a pretty rock solid ground not to soft like the hills of esco. and let me tell you this is where i fell in love with this little thing ! had racked up 3 nade kills by the end of the day every time i tossed it it went off and felt so good every time. as for volume its actually a pretty good little pop had one player jump and it was outdoors. needless to say you know when it goes off next to you. i wouldn't put to many bbs in there for it takes away from the pop i feel like but i could be wrong. its also easy to make back up pins for this model if you loose them. as well do not over fill this grenade .5 seconds to fill it you will know when its full the pin will have tension on it. also when you break it cuz you will its because you put too much green gass in. very simple i mean simple fix. unscrew the top portion of the grenade the part that has the flat sized this will let you into the internals. if you cant with your hands get a small allen key and use it as a lever where the pin goes and a wrench on the flat part. unscrew and inside you will find a ball and a few other parts dont mess with any of it just find the red or black o ring that is floating around in there some ware its rather large because it fits on the threads to make up the air seal. find it grease it do what ever you want to clean it but put it back onto the top of the threads where there is space for it you should see it. theirs you tube videos on how to maintenance your JR2 as well good luck hope you like it as much as i did.

"This is amazing! I highly recommend it. It is easy to use, simple, resetting is very quick, and it is nice and loud. It has minimal moving parts, is hefty, durable and small. A few important things to note:
-It only takes half a second of time to fill it with gas. Any more and it will knock the seal loose and you will have to do a little (as in 3 minutes at most) work to reset the seal.
-It is pretty useless out doors unless the ground is hard or you throw it at a tree. If it lands in mud or soft dirt, it won't likely go off.
-DO NOT use the retaining lanyard it comes with. That thing WILL come lose and then it will be a pain to find the other part. I suggest some very thin para-cord or you can use a hair tie that is cut to be one long piece.
-Before you use this, mark it with reflective or neon tape and put your contact info on it with a note that it is not to be thrown away. It is so small that people might mistake it for a thunder b core and trash it.
-Don't bother using powder or bbs in the base because while it may work, it really is pointless and will take the "boom" out of it.
I have to reiterate that this is an amazing grenade. Indoors it pops every time and can be primed with barely any gas right on the spot. Try it out and you will be very pleased. The only mistake you can really make is not buying two. Haha!

"By far the easiest, fastest to set up, most effective grenade ever made. But the cyclone holds the best overall title without competition.
It's not thunder b loud, but it's louder than the cyclone.
It does throw a few bb's but not consistent or far.
It seems like it might last longer than most grenades due to it having hardly any parts, a o-ring, a button and a 50mm-ish bearing.
Add in the Non-Map factor and this is a great, cheap, highly reuseable, long lasting grenade.
Only flaw is the cheap dental floss they give you to tie the two ends together. Mine broke after 1 use.
I'm sure a shoe string will work just fine as a replacement upgrade.
