We have been using the JRS Eco-Wifi for about a month now, and even with our old BT Extender (to get my WIFI through the thick granite walls (we live in Scotland)) it works very well. Compared with the BT (British Telecom) Hub (router) the signal is a tiny bit weaker, but it is more than strong enough to do my work in my small office.
For the people who are considering buying a JRS Eco-Wifi you can amend the strength of the signal, so no worries if you are concerned you will lose too much wifi strength.
And, health wise, I rarely have any headaches now, which is an absolute miracle. The only thing I hope, is that this extreme exhaustion will go away, which I already had before we purchased the JRS Eco-Wifi. So the exhaustion must be something physical or perhaps phychological, rather than caused by the radiation of the old BT Hub. The Trial continues …..
