They had similar problems with their football (as in soccer) streams in europe at the beginning. However to be fair they improved a lot since then and it's pretty stable now. One has to consider that it's live and while I'm sure Netflix or other big players would do a better job, being able to buffer makes this much easier.

I think DAZN is an awesome package with lots of relevant content for a football (soccer) enthusiast like me at a very fair price.
