I just saw this, and they look pretty awesome!!
Im gonna phone them and find out more 2moro, as it doesnt give a lot of details on the page, and google yielded nothing more that i found useful..
theyre a pretty good price as well, with the basic ones cheaper than an hfm BFG
Enjoy,
Tom

Considering that it doesn't fly apart into several pieces (you retain the pull ring), uses no pyrotechnics and replacement parts are readily available, they've gotten many "thumbs up" around here.

is it just the co2 bulbs that need to be replaced or the diaphrams as well?
because its 30quid for 12 bulbs and diaphrams, which if they needed to be changed after each use, would mean just under 3quid a pop, in which case you might as well use normal pyro.

exactly what i was thinking. But i think the burst diaphams are just if you want to use bb's as well. In which case a Co2 bulb is like 60/70p.

The black cap and the co2 capsule have to be replaced every time. I believe the guys that have them here found more cost effective replacements for the co2, but the diaphrams have to be purchased from the manufacturer.
While traditional pyro might be more cost effective (and more fun), state laws and environmental concerns here preclude the use of those items.

Also on ASC claimed to be a realistic 1.5secs "Time from spoon release to explosion is approximately 1.5 seconds"

I've not seen the 8g CO2 bulbs it uses before, Airsoft World sell the 12g CO2 bulbs on their own (for gas guns), so by the looks of it you're forced into buying Charges Pack.

Ebay seem to have them which i guess means they are out there and available somewhere.
Edit: Seems the link doesn't work, search fro 8g co2

Aha, good point! I see, you can get 100 8g bulbs for £32.50, not bad at 32p a pop then

The 8g ones have been around for yonks, my dads mum had a soda stream thing thats like 30 years old that takes them
These nades are a bit expensive for the UK though really, at least with BFGs the blanks are pretty cheap and you do make a saving.
I'll stick with £1.60 Mk5s though

well not really as you need the rubber diaphrams as well as there only 1 use.
there a nice idea but not really cost effective in the uk.

They work quite well, and really are a distraction indoors. Outdoors, it isnt soo much. They are loud still, but its dispursed, compared to bouncing off the walls in indoors.
The diaphragms cant be reused. They are a plastic top that screws on and when the co2 is poped, it builds up pressure and blows the threads off the plastic cap, thus making it unable to be re-used.

Thanks for clearing that up! That means that the operation cost of these sky rockets - £30 for 12 uses takes the cost up to £1.67 per pop. And £65 with THREE uses for the grenade.... eeehh errrrh!!
Seeing as I just bought 50 pyros from Airsoft World in a bulk of 50 for £1.50 each - fair enough some sites don't allow pyros but given the choice... Also lets face it after you throw something away you don't really want to be spending the next 5 minutes looking through bushes trying to find it again. Would be ok for CQB areas where it'd be easy to find.
Nice idea. Too expensive.
Saying that I've been chasing the dream of a decent reusable gas grenade for ages, still no joy. I want something that'll send BBs flying in all directions.
I can only see this grenade being used where you absolutely totally had no other choice in the matter.

Let me start by saying I own a pair of these. I'm not sure where that dB measurement was taken, but they *might* be that loud if it went off right next to your head. I've blown 'em at my feet in an enclosed concrete room and had no problems. They're quite comfortable. AND for the U.S. they're great because they're not pyro based. Anything pyro based is a non-starter in a lot of the country, and particularly here in the Peoples Republik of Kalifornia (fire bad!, FIRE BAAAAAD!!!)
