Last week when I was looking at Bolts on Amazon, their Amazon ratings were pretty bad, like 2.5 stars and lots of 1-star reviews. I just looked at them again today and suddenly they have 4 stars. It looks like Amazon solved the low ratings on the Bolts by combining all the ratings for all Roamios and Bolts into a single rating. This isn't just limited to TiVo. Amazon has been doing this sort of thing with other products for a little while and I find it really annoying because it makes it harder to tell what product is really being reviewed. But it's probably a good thing for TiVo to artificially inflate the Bolt's Amazon ratings by mixing them together with ratings from old products they don't even sell anymore.
