I wanted to post an update, mostly for Stryc's benefit (hopefully).
My X52 Pro broke last Thursday. On Friday morning I called Logitech and the guy opened a ticket, took my name and e-mail address and said someone would e-mail me in 24-48hrs.
On Tuesday morning I figured the 48hrs was up, so I contacted Logitech through the live chat on the website. I again gave my name and e-mail address and was told I would be contacted in 24-48hrs. I told the representative that I was told the same thing on Friday and had not heard anything. He of course apologized and told me someone would contact me. Didn't feel like I had much recourse so I came looking for other reports which is how I found this post.
Well, surprise surprise, "Heather" contacted me only a couple hours later. I did notice that the ticket number in the e-mail is the one from the live chat, I've still never been contacted with the ticket number that was given to me over the phone on Friday.
"Heather's" replies have been very fast. The english isn't perfect, I suspect an asian call center, however, she's exchanged several e-mails, always quickly. We completed all of the standard business that goes along with a warranty claim, I had to submit some pictures of the failure, I had to submit my invoice from Amazon, and all of my contact/shipping information. I did find it slightly odd that each of these things were requested in separate e-mails. Like, she asked for pics, I sent them, she asked for my invoice, I sent it, she asked for my shipping info, I sent it. But, all of the replies were fairly fast, so I have no real reason to complain.
Earlier today I was told that they are currently out of X52Pros, she asked if I would accept an X56. I sent her back an e-mail verifying that the X56 would be the latest version, which she confirmed. I also asked about the ETA on an X52Pro if I went that way, and she said there was no ETA. So I told her to go ahead and ship the X56. I'm not sure what the shipping time will be on it, but I'm hopeful it won't be too bad.
All in all, I'm pretty happy. I would encourage Stryc to contact them again because my entire case was completed about 27hrs after I logged the issue with the live chat on the website. My initial telephone contact does seem to have slipped through the cracks.
