I've used Send It for several years now as both our in house host of weekly events that we run at work (via Zoom) but also hosting external speakers who come into town via Skype/Facetime etc.
The customer support is excellent - they are always very helpful when you need them! Nothing really comes up too often where there's been any issues or problems though so this isn't something i'd actively recommend looking elsewhere if things do start going wrong!! We're able to have these regular meetings without having people physically travel from far away which has saved us time costs plus reduced risks associated wtih COVID19 / Coronavirus restrictions being put place around social distancing measures during lockdown times.
