I have previously subscribed to several Zoolz / Genie offers, and I have also invited several of my friends to do so. Although these offers were “for lifetime”, Genie told us after a few years that we had to pay annually to continue to benefit from them.
One could have thought that it was a management error of their first offers, but since they go on in the same way I consider that they are thieves and liars. So expect them to ask you to pay in some time to extend in time this unlimited offer…
