As my title says really. For this price, lifetime, and with the options it offers, you can't really complain. You will not find a better offer.

It doens't feel as polished as other such as Cal.com might, but I don't miss any major functionalities.

In my opinion, it needs more customisation options for the bookings screen (ability to set up backgrounds, colours in each meeting, etc.), and some more flexibility on custom notification emails (I had to duplicate every meeting type on my page to set up a Spanish and English version, given that notification emails cannot be set on different languages).
