No complaints so far. The caveat is that my broadband download speed is sub-100Mb/s (around 90), so it's hard to tell if these ultra thin cables are really giving me the highest bandwidth, but there's certainly no slow-down from what I had before.My reason for getting these was related more to cable management than speed - both my router and switch had problems with the really thick round 5E cables I had; the switch - sitting on the top back of a bookshelf - would tip backwards from the force of the cables plugged into it. These thin cables make the stress on both the cables themselves and the devices they are plugged into much less.EDIT: I've now had GB service for several years, and consistently get 850 to 950Mb/s , which is what I'm getting from my provider, so for not being "twisted pair," these have functioned phenomenally, and are really convenient, easy to run, and space saving. Very happy.
