The only time I even consider looking at videos is if I have a new RTA that I need some building pointers on, and even with build videos I do that so little now that I'm more experienced... but occasionally I might need some tips.
Anything else I watch what people say here on ECF after they have owned and used a product for 6 months to a year... if the remarks are still good overall, then I make my purchase..
even those here who do
reviews don't use the product long enough before posting a review to be able to say very much as to the things that interest me most - which is longevity. Is the thing going to break in 3 months? have board problems in 4? can't say things like that if you've not used the thing more than a tank or two before going on to the next mod review.
Hand feel, weight etc is great to know but if there's no longevity it's bunk.
