Another vote to be careful with EA and even some newly released products in the main store. The first iteration of second gen switches such as US-L2-48-POE (see
here) were in the main store but were then discontinued which means they could quickly become useless due to lack of software.
I think EA should be considered 'prototype' hardware with alpha software. Early general releases are then more what many consider the current EA to be as even then there have been a few early hardware revisions to fix significant issues.
These days I wait until a new Ubiquiti product is released few months or more and keep a close watch on forums before purchase.
