Reply To: New Brooklyn Eruv: Time to Accept?

Neville,
As I wrote in an earlier post. If you want to know the basis of the GBE why not reach out to them, they’d be glad to explain it to you.
Anyway, if you ever learned the pertinent halachos, you’d realize that the halachic mechanism used is not involving any mekil shitos. It’s just as good, and perhaps better, than many out of town eruvs you’re used to.
And no, nobody is following them blindly. One either has a rav to ask his shaila, and if not, and he chooses to rely on the rabbanim behind this eruv then he is in pretty good stead, better than anybody opening seltzer bottle caps on Shabbos, even plastic ones for which The heter isn’t nearly as clear in the gedolei haposkim as is the eruv. (Although it is perfectly fine if one follows the matirim for the bottle caps.)
