Well my experience of Impero support previously was that we would tell people about how good it was now it's shocking. Since December we've been trying to get a iPad to connect for a visually impaired student who needs to be able to view the teachers screen from up close but we just can't get it to work. We've gone through loads of upgrades as "there's a known problem with this version" and even one of those upgrades went completely pear shaped and had to downgrade 2 version before being able upgrade to the latest version (2 weeks lost there trying to fix it). Anyway, it's May and I had one email response on the 28th April saying "What issues with the iOS client are you having at the moment, is it deployment/installation or connectivity related?". I very nearly did go and bang my head on the wall I was so frustrated. Anyway, I've restrained myself from commenting but can't hold back any more.
It's good to know that there is an alternative as I'm now considering one when the renewal is up at the end of the year. Hopefully this might trigger a response of some kind (any response would be good just to know you are still there).
