Pretty good idea, think of it like an enhanced version of comixology, but in Europe. You can subscribe(limited selection but you do get more than first book of a series unlike comixology) or you can 'buy' individual series and titles.
Downsides are drm of course, and you have to be connected to their site when you read(pc, ipad, android, N Switch), and the fact the 'fine print' only guarantees 'bought' titles for six months. ....Actually, the latter is a bit worrying.
As it's based in Europe, it also has a large selection of European comics. Unfortunately Asterix and Tintin not included...
