Opener works great, no louder than any other opener. Installation fairly easy, all the parts needed are in the box. Instructions are written in English.
I noticed that when I received the kit in the mail that the new sensors (41A5034) were a different size than the originals (41A4373). As a result, I had my doubts. However, they worked just fine after retrofitting them to my original brackets (the kit brackets weren't compatible with my door rail, etc.). Good price too!
