garage door openers problems

I've never had a door opener with sensors, but deal with such sensors all the time at work.
I've only ever had old, old openers where the door was directly onto the alley out back, where no kids would be ever be darting about anyway.
Saves a lot of snow shoveling for sure, and I can't imagine an attached garage in front, where this might be desirable.
Mine will reverse if blocked, but I never got the remote to work in 23 years here, just never seemed important enough.
