Evidence that could have come out badly. A great review states how long the test ran, on which devices, at which hours, and what failed during it. A glowing review reports perfection across seven services and never names a device or a date. The difference is falsifiability: one makes claims you could disprove, the other makes claims that cannot be wrong because they cannot be checked. Bandwidth is a good example. A review that says the picture looked sharp has told you nothing. A review that says 4K ran at roughly 15 to 25 Mbps and consumed about 7 GB an hour has given you a figure you can confirm against your own router traffic in a single evening.

1. 1Names devices, hours and test window
2. 2Reports at least one failure
3. 3Uses bitrate and data figures instead of sharpness adjectives

Because live sport is the moment people judge a service and cancel it. Recorded content is buffered ahead and hides weakness; a live feed arrives as roughly six-second segments in real time, so any stall longer than the buffer becomes a visible freeze at the worst possible second. Peak demand also lands on the same few streams at the same time, which is exactly when oversold server capacity shows. A review that only tested a film catalog at 2pm has not tested the failure mode that matters. If a review praises a service without ever describing a live event during a busy evening hour, it has skipped the only test most readers care about.

1. 1Live streams arrive in ~6-second segments, so stalls are immediately visible
2. 2Peak-hour concentration exposes oversold capacity
3. 3Off-peak film testing proves almost nothing

Six of them. Bitrate and hourly data use per resolution, because that decides whether your connection and any data cap can carry it. Codec behavior, since HEVC delivers a comparable picture at roughly half the bitrate of H.264. Uptime with units, where 99.99% is about 53 minutes a year. Simultaneous connections as a number, separate from installs. The refund window in days, with exclusions. And the total price of the term rather than a monthly figure. IP4KTV's version of that list is 4K at roughly 15 to 25 Mbps, 1080p at roughly 5 to 8 Mbps, 99.99% uptime, 1 to 5 connections with unlimited installs, a 7-day money-back window, and $120 for twelve months.

Run the same measurements on a short paid trial. Check your router's traffic graph while a 4K stream plays and compare it against the 15 to 25 Mbps range. Open a second device to confirm the connection count. Switch away from a stalling channel and back again, because recovery on switch-back means the session stalled rather than your bandwidth failing, which is the single most discriminating test available and almost never published. Then note how long activation took. IP4KTV activates in about five minutes and sells a $5 24-hour window for exactly this purpose, with no card stored and no automatic conversion into a plan.

1. 1Compare router traffic against the stated bitrate
2. 2Switch away and back to separate a stalled session from a bandwidth fault
3. 3Time the activation rather than trusting the claim
