I did the same thing, created an account just to comment on the OPI dont have any Buffering issues. I created an account on Tom's guide just to comment on this. The reviewer is horrible and sounds like he's paid for this review.... From cable company's or something Clearly something is up with his router/network. Sheesh, horrible review on this. Firestick 4K works fantastic. Multiple Devices with Buffering issues... yea lets blame streaming sticks... Probably on 15mbs DSL speed using a 4 year old router or older.
