Yes, I remember this company being around when I first became ES (around 2001). I even called them on the phone asking about these monitors, but they admitted that what they had probably wasn't good enough for me. And the meter they had in their website photo sitting in front of their LCD monitor was a 60hz magnetic field meter, which would display zero for most any LCD monitor (shielded or not).
Haven't heard much about them since, even though I've been on ES groups for over a decade.
Yes most macbooks now only have wifi, but you can use a thunderbolt to ethernet adapter if you want to use ethernet cable. Regarding some macbooks I think dirty emf from the electronics are worse than the wifi, at least for me as I dont react to wifi anymore. But everyone(many) reacts differently.
Some are but they can all feel different, wifi alone makes me extremely unstable and hyperactive at first and then just runs my body into the ground like anything else taking my senses down with it. Computer towers and game systems are absolutely terrible offenders these days, the only reason I'm on one right now is because the one I built I chose a very good emf blacking case, it's not perfect at all times but it's manageable. I bought another tower a while back for a different purpose and couldn't even use the thing and I wasn't willing to buy another corsair carbide quiet model and redo it just for games. I also tried both a Xbox One and PS4. The Ps4 is somewhat better but I can't take using the Xbox One for too long without getting myself sick. We need more built in protection in electronics, it's not a difficult task but I'm sure that addressing the safety issue would open a very big can of worms given enough of the public believes it at all.
