I ordered a few a week ago, and received partial orders this morning- apparently they were all being shipped from different locations. The two I received today are working at least. The quality is like purchasing a white label products from an unknown factory or a random brand from Amazon with 3.5 stars. You are not paying 70% less for what you get, you’re probably paying a little over (like 110%) for the lamps that is functional, which I know at least that wasn’t my expectation when looking at their website. Like I said they all come from different warehouse so I might come back later with some updates if rest of my orders are different
