I am looking for a good recommendation for an IPTV service that does the following:

• Runs well off of Amazon Fire Stick
• Doesn't have buffering issues
• Doesn't have to necessarily be 1080p, in fact I don't care about quality if it doesn't pause to buffer.
• Doesn't have buffering issues when traffic gets heavy, so I can watch UFC on Fox Sports during prime time with the same smooth streaming as when Fox Sports is playing something boring in the middle of the night.

If you're an IPTV provider, don't recommend yourself unless you can back it up with a free trial. I'm looking for the input of users only.

If the streaming service turns out to be what I need, I will def shoot a small financial reward to whoever recommends it some way via PayPal or something.
