Everyone writes reviews based on Saturday night. Peak time. Servers are ready. Staff are awake. Of course it works.
Nobody tests at 2 PM on a Tuesday. That's when lazy resellers cut costs. Fewer servers online. Slower support. Cheaper bandwidth.
I started testing at random weekday afternoons. The results were brutal. Three "highly rated" services failed my 2 PM test. Buffering. Slow EPG. Dead channels.
A proper British iptv reseller passed easily. Same performance as Saturday. Because they run full capacity 24/7.
The British iptv service I use has no "cheap mode" for quiet hours. Servers are always at full strength.
A bad IPTV reseller UK scales down during the day. Saves money. Hopes you don't notice. You will notice.
Next time you read a review, check when it was written. Saturday night reviews are meaningless. Tuesday afternoon reviews tell the truth.
