A good well designed product is sometimes worth the cost that one may not understand until owning it themselves, then wonder how they lived without it.
I'm your average middle class RFD'ER looking out for deals and whatnot, bought a robot vacuum for the simple convince. Some loved it and bought themselves others said it was a wasteful purchase and I'm lazy.
Some will pay $200 for a quantity trashcan while others will shame them for the wasteful purchase.
To each their own
Live and let live
Enjoy the deal for those that purchase it.
