No, an 8335w garage door opener is not the same as the B1381. This Chamberlain Group B1381 garage door opener is a better one. It has all the smart features that make it easy to access, like connecting to wifi, Wink, Key, Google Assistant, with Max lift power system-1.25 HPS, which are of low quality in 8335w. Also, B1381 is ultra-quiet too, unlike the 8335w garage door opener.
