Never buy. There is no robust studies to prove it is harmful. And there is also no robust studies to prove that is is safe. The reality is you need to do a trial which requires sufficient sample size, longer time frame and regular medical check up to do that. Not many Gov will spend that kind of money to do that. If proven harmful it will cause panic. Of course developer won’t pay for something that will prove negative. So the best quote is “no evidence it is harmful”.
But some people who have stayed near this structure feel that their health is not the same as before, some have headache etc. of course some with higher tolerance won’t feel anything but it doesn’t mean there is no harm done. Even wifi at home is not encouraged to be turned on 24 hours/ day. Just that we won’t feel the effect so soon.
