The t8s plus is probably the best box in the Droidbox range. But let me set your expectations. On ANY streaming box, regardless of manufacturer, live streaming can be hit or miss. Primarily due to contention at the servers hosting the stream. It is the difference between a free and a paid subscription via the usual suspects (sly, vermin, Beatty etc).
Some organisations of dubious legality also offer cheaper paid subscriptions for streaming boxes. They claim to offer a better service due to more dedicated hosting servers. Something you can investigate if you want a more robust service.
I still think that even taking account of the frustrations involved (getting kicked off streams, searching for a stream in the first place, buffering etc), it is worth persisting with though.
