I have been using Endless OS for some time. I have installed it and reinstalled it several times. About three weeks ago I decided to do another fresh install and this time around I decided to download the full 14GB (English) ISO. The download took a long time to complete, but the resulting ISO flashed to a USB drive and installed easily.
It really makes a world of difference. I find my fresh install with all the extra added content to be much more enjoyable to use. The content is useful and well presented. Indeed with the full setup one can spend a great deal of enjoyable time exploring without many resources for the internet.
Before I downloaded the big ISO I looked through the Endless web site to see if you perhaps sold a pre built ISO, like Ubuntu does. It appears that Endless is no longer selling any thing besides the extra codecs. I was really impressed with the full Endless package and it would be nice if you offered USB sticks for the full install. I of course hope you do continue to make your computers.
