This makes the product sound terrible. I really doubt they need to make screws or switches. I thought the same thing. It reminded me of the genie garage door openers at my rental property. The end limit switches are were obviously designed in house and are basically two strips of some copper alloy spring material that come into contact as the door passes. The problem is that a garage is a dirty/corrosive environment. On a yearly basis I have to sand the contacts. All this to save a few pennies vs just buying a standard micro switch! I can't determine if its was incompetence, cost cutting, or just planned obsolescence. Of course, I just posted a few things on another board about how I think the lack of software licensing leads to the lack of "software standards" where everyone and their brother is basically doing the equivalent of building their own screws, with their own thread pitches and head patterns or using whatever happens to be "cool" this month.
