For those who don't know much about adslmax, years ago he always used Entanet resellers. There were half a dozen or more in those days.
Entanet resellers had one-month terms on ADSL, but on a migration out the unused part of the month's subscription was refunded.
He did at least one speed test a day, and as soon as he got one 1Mbps below normal he would ask for his MAC, and migrate to another Enta reseller. He used some of them several times. Staying for two months with the same one was almost unheard oh f).
