I've posted a few times on the forums about our product when it comes up... This seems to be a reasonable thread to post a reply.
I did receive her email when she sent it. When I answered, I hit reply, and it went to the address of our web email form and never got the bounce message. So as I said in a direct email to her, that was my mistake.
I'm sure a follow-up email or phone call (we have a toll-free number on our website) would have been adequate, instead of waiting a month and posting like this, but I guess some people think the squeaky wheel gets the oil...
As for buying two Techshells.. Totally unnecessary. Our warranty is for a year. There's not a Techshell out there right now that's not covered for a problem in manufacturing. That's the only way I can imagine one got cracked. They're hard to break deliberately, let alone by accident.
In most cases, a shell with a problem is replaced within a few days of the complaint. Usually, we do not require it be sent back, just a photograph showing the defect or damage. No need to waste shipping packaging or fees on a product that can't be repaired or re-sold. We feel this is a pretty customer-friendly policy.
As for scratching, kkat69 is correct that at least a little care needs to be paid to what is between the shell and the laptop. Obviously, the laptop needs to be free from dust/grime/sand/whatever before the shell is put in place. Periodic cleaning is a wise thing to do, as well.
We put so many shells on and off our (personal and business) laptops so often, I'm quite sure we'd be the first to know if the shells were causing scratches on their own. My 4 year-old 12" Powerbook G4 looks brand new.
I hope this will help clear things up.
