Damn that sucks! It could've been a combination of things, heat, pin, dull drill bit, drilled to fast, too much glue, or just pure bad luck. We will never know. The so called thin shells isn't the cause or the 900 global plant. Don't believe the nonsense some people say on here.
Me and my buddy have been throwing Seismic for 2.5yrs, I haven't had one crack on me, and still have my first BLackout, well over 1000 games. My buddy has had one crack on him, an Aftermath and he has 2 of everything Seismic put out. Cracking happens with the invent of these super soaker covers, some sooner than others. Does it suck, hell yeah it does. But I stand by Seismic products, and I hope, and am sure that Ryan will take care of you. If not, contact me and I'll ship you a brand new one on my dime!
