新蛋翻新版,可直接购买,估计是黑五退货版本。路由器对外观要求不高,翻新版质量问题几率不大。国内对应版本RT-AC66U,京东最低价到过899,亚马逊第三方849。美亚RT-AC66U称为Web版,最低到过130左右。RT-AC66R称为Retail版本,常年在135左右。

关于"R"和“U”版本的区别论坛上有许多,尚无官方定论。但第三方固件asuswrt-merlin的开发者称两者无任何区别:

RMerl/asuswrt-m...

NOTE: all the "R" versions (for example RT-N66R) are the same as their "U" counterparts, they are just different packages aimed at large retailers. The firmware is 100% compatible with both U and R versions of the routers. Same with the "W" variants that are simply white.
