I'd never trust adverts out of nowhere.
I'd (and never do actually) trust adverts at all. I allow myself to claim that I am mostly immune to adverts since I always assume that everyone advertising anything just wants to scam me. this leads to (sometimes excessive) amounts of research before deciding which product suits my needs, but on the other side, I haven't received a bad item for a very long time - well, except from that stick welder, which was not to bad for the price I spent, but died at the second use.
this is by two former ISP employees who knew a secret and made this device that can bypass your ISPs bandwidth throttling
That claim alone screams bullshit to me. If it would even be possible to bypass bandwidth throttling from a remote point without changing your plan at all there would be tons of people out there doing so. Heck, I would combine 20 of those devices! My ISP says I can only get 100MBits download/40MBits upload but they sell a way more expensive plan to double up to 200MBits/40MBits.
I should try to buy 10 of those for the beginning, than I can get 1GBits download and 400MBits upload! I actually don't know what I should use that for, nor which Server could provide such speed at all (many aren't even able to give the full 100MBits...), but hey, why wouldn't I if I could?
On the other hand, that would be the rates for parallelling those things. If I could somehow connect them in series.... how does 10.24 TBits sound?
