Historically the range on these is between 50-150m, considering its a ring and the fact that you can't always lock them down... it seems reasonable to me.It's likely a 1 of 1 and the offer is only 100m so far? Cmon, some of you guys are charging us 450m on safe's for 1 of 50 EM drops.
Pony up, this is a nice item!
