I've been a TiVo customer since the Series 2, and every TiVo I've owned (Series 2, Premiere, Roamio Plus - all with Lifetime) have all been rock solid. I still have my Roamio, which if it wasn't for its painfully slow streaming apps (Amazon, Netflix) I wouldn't even consider the Bolt. I know I can just buy a Amazon Fire Stick for better performance, but I'd rather be able to do everything with one remote and input. The amount of threads related to the Bolt's high temperature issues have me very concerned about its long-term durability. I don't want to be 2 years into ownership of a Bolt and have the hard drive or main board crap out. Are my concerns justified? Is there any pattern of several year old Bolts failing? Thanks.
