A:Answer The new elites are based off the redesigns of the the second generation controllers. I could very well be wrong but I believe they changed to individual bumpers versus the one solid piece it used to be. I've replaced a few of the first generation and elite broken bumpers and they often break towards the center where the piece is the thinnest. Changing to individual pieces eliminates this center piece all together. As far as adhesives, everything that I've seen hints that they've fixed the problem of the rubber coming off. Here's to hoping they did fix it. If nothing else get the geek squad warranty and it'll cover the rubber coming off IF it does since that is normal wear and tear which IS covered by the warranty. I don't work for best buy, geek squad, microsoft or anyone else. This has just been my experience. I recommend contacting microsoft support as they have been helpful towards me multiple times even with just general inquiries.
