Signed up to the pioneer service (== vaderstreams) for one month here: https://my.iprocket.net/ with the kodi (with web viewing) option.
Applied the "pioneerreddit" promo code just prior to checkout and got 10% off which made the total $11.95 for the month.
Ran the service in kodi on an nvidia shield 2017 model running android TV hard wired to a stable internet at ~70Mbps downstream
The next part will apply to vaderstreams regardless of reseller: I found the vaderstreams kodi addon to be a useless buggy p.o.s. There are more details here along with a possible workaround: https://www.reddit.com/r/VaderStreams/comments/75z2ve/service_stopped/dorqjjz/
Putting their kodi addon disaster to one side for a moment, I have found the vaderstreams backend to be reasonably solid and the streams are good quality. Now that I've found a kodi workaround that works for me, I'm in two minds whether to renew for another month or bin them off.
If you have a shield and want the best experience (minus VOD), download TV IRL. It integrates the m3u and xml files directly into the "Live Channels" app that is natively built into Android TV. Channel changing and the EPG is smoother than a cable box, even on my low spec Nexus player!!
For the most part (in my experience) most IPTV ran through KODI is flaky. There's a reason dedicated IPTV boxes still exist.
FWIW, I now prefer TV IRL on the nexus player over my Dreamlink T1 Plus.
The downsides are no VOD and no channel grouping. On the bright side, you can hide the channels you won't watch.
