I was very hesitant with all the reviews but I bought this to listen to books on tape. It has never died on me and I work 6/7 hour shifts. It's fairly large but with the right ear piece stays in. They also include over the ear adapters which help keep it in. The only down fall I would say is that the plastic ear pieces break very easy.

After receiving at least weekly blue screens, then being unable for the past two days to download StopZilla's updates and twice getting blue screens when I tried to perform a full StopZilla scan, I deleted the program altogether and replaced it with SuperAntiSpyware's Professional Edition (which I have also reviewed on Amazon's website), and I am pleased to report that I no longer encounter such problems. StopZilla's Tier 2 help desk ignored my voice messages and occasionally responded perfunctorily to my emails; Tier 1 kept trying to charge me a "bargain" price of nearly $100, even though I own four lifetime subscriptions. Other problems: apparently incompatible with Microsoft Security Essentials; some updates prevented Windows from starting without resorting to System Restore or deleting the program via Safe Mode. Level 2 technical support, reachable via 1-877-877-9944, extension 220, may offer a refund, but Accounting will probably deny it, as happened in my case. Level 1 support keeps trying to charge an additional $99, supposedly discounted from $149.
