I saw the $279 deal for the Bolt 500g 4 tuner refurb last week. I had no NEED for replacing my Roamio, but, I was thinking I would love the new technology. I could set up the Bolt with my cableco and use the Roamio with an Over The Air Antenna (OTA). (The 4 tuner versions work with either cable or OTA.) I was also looking forward to Out Of The House Streaming. (OOTH) I also purchased the vox remote at 1/2 price ($20) to try out the voice features. To me, the vox remote is useless. It can't even use commands like "channel up" or "channel 2". (You need to know the station name.) If you have to use the remote to select voice versus using the remote to select "play", it is still just one button. It just seems useless. So that seems like a wasted purchase, although not a deal breaker. And maybe it's functionality will improve. Since I could not stand the Tivo Experience 4 (TE4) "experience", I reverted back to TE3, losing the voice functionality of the VOX remote. At least the downgrade was smooth. This also turns off the Bolt's bluetooth support, forcing the remote to become IR. So, I would end up with another white IR remote, not even RF. THE PLUSES 1) The TiVo Bolt is fast, even when downgrading the software to TE3. 2) Out Of The Home Streaming is great (if it works) THE MINUSES 1) In my case, OTA worked fine, but there is a tuner problem when connected to the cableco. It shows V52 no signal on the top tier stations . For me, this is THE deal breaker causing me to return the unit. I am certain the unit is defective because the Roamio works fine using the same exact Coax as the bolt, while the Bolt says I have little or no signal. Even the Comcast Tech agreed, because she said that many Bolts have problems with the signals. 2) No RCA Video Out, only audio. I use Slingbox, but if the OOTH Streaming works, I could use that. I was going to try to use the audio output only, since I listen to a music channel at work with my slingbox. Video is not really needed. Not a deal breaker. But it seems like a cheap savings on Tivo's Part. There is a splitter I found for $25 that would have given me what I want. 3) The fan on my unit was BRUTAL. It was actually causing my table to vibrate. I fished around for a solution (since it is a common complaint), which I could made work, so it is not a deal breaker. But, it is crazy to have to deal with this out of the box! If it is a bad unit because of the fan AND the tuner, then that is just real bad luck! I should point out, from what I've read, it is the method TiVo is using for cooling that causes this vibration. Changing the power source cures it, or of course unplugging the fan cures it. 4) I could not get OOTH Streaming to work on my PC. That being said, when I reverted from TE4 to TE3, I did not re-activate the streaming app at home. So, when I was at work, the app on my phone would not work, and TiVo.com said "This feature is not supported at this time." When I got home, I re-activated streaming and the Android app started working. So, it is possible the PC version is working, but since I am returning the unit, I'm not sure if it works. Still, while a "nice to have" feature, it is not a deal breaker if it doesn't work. 5) I am NOT happy about the 2.5 inch hdd since the prices are crazy for an upgrade. I could have gone the external route with a cooling case using a 3.5 inch hdd, or I could pay $140 for a new 2.5 inch hdd, but I decided I would live with the 500g hdd. So, while it is not a deal breaker, it makes the Roamio look better and better as I write this review! In summary, I am grateful that TiVo offers a 30 day money back guarantee, including shipping. I'm also glad that I got to try out the Bolt. I do not like change, that is a fact, but I could live with the changes if the core part of the product worked which is WATCHING TV. So, if that part worked normally, I would still be using the Bolt. But, I do NOT think I will go for a new Bolt until I'm forced to replace my Roamio.
