We'll try diagnosing your problem via email to determine what replacement parts you may need. If that doesn't work, or we determine through the communications that the repair is not field fixable, we'll take the grenade back for refurbishment. Most repairs are turned around in a week free of charge on parts. I think our policy is to offer free return shipping, but you pay for the shipping on the way in.
One way or another, you'll get that thing working again.
Please don't PM me directly for repair advice. We have a good repair ticket setup and the boys are running it well. Myself, I'm not good with regular email responses. I spend most of my days arms deep in some hunk of misbehaving heavy machinery. I fix the shit that makes the shit and the boys assembles the shit that occasionally needs fixing.
