Have Liftmaster 8500W on a 9 x 8 OHD and thinking of putting an opener on the 12 x 12 door. 8500W has worked fine - have read of some early issues but this was installed about 2020 and I think the issues were resolved before that. Chamberlain is about $200 cheaper and looks to almost identical and from what I have read the guts are the same (from the internet so it might not be true but seems likely). Might move the 8500W to the large door because the newer units don't include physical cable tension monitor and the small door is high lift which greatly reduces the chance of loosing cable tension. Both the new units are Security+2.0 which will work with older remotes and also some DIY home automation links so do difference there. The automation link should allow slight opening for ventilation. Anyone know how similar these are or any reason to pay the additional for the Liftmaster?
