I've played around with a few different airsoft claymores, and from what I have seen they all work off the same concept. I'm sure some of you have seen Novritch's recent review of yet another over priced commercially made claymore, and there are hundreds of 14 year olds uploading their mouse trap claymore builds to YouTube, but today I found another option that actually seems decent, and decently priced. http://m.lightake.com/p/electric-re...-bomb-outdoor-cs-equipment-green_2335510.html It's made for those water ball gun things you see at Wal-Mart, but could obviously be used for airsoft. There's even a review. The issue I have seen with most commercially available claymores, is they are too sensitive. The one I own (I believe it's a CYMA, probably wrong) likes to go off as soon as you pull the safety out, it's not a very good design. I've even had it go off with the safety still in. This however looks a little "safer" in that regard, the guy tosses it around on the the table during his review, and even moves it around freely after removing the safety tab, and it doesn't go off. It's got a clacker, instead of the not-very-milsim-looking key fob that you see with other models. The other thing, it's cheap. 35$? Sure, the quality may be sub par, but as long as the safety holds and the remote works I'm happy. Most people don't like to bring out their $80-100 Claymore because you so rarely get to employ it effectively, and it's not worth loosing it if something happens. I'm the other hand with a 35$ mine, you wouldn't have to fear someone dragging it across the floor by accident after they get tangled up in the trip line. What do you guys think?
