To cut a long story short, I am now banging my head against the wall that I haven't tried this from the very beginning. That would have saved me a LOT of money, time and tense nerves.
This is SUPERB. It does what is says, with a very simple and impressive manner.
Configuration is the only con i found, you might need help with this, but SUPPORT IS AWESOME :)
People from support responded to my email in just a few hours solving all the issues I had. Thumbs up.
This is definitely worth the money, if you are looking for a live support extension, look no further.
PS. I LOVE the "Push URL" feature. It allows you to direct your visitors browser to any url you wish, instead of just sending them the link. Awesome.
I had two small hickups, though. Firstly, by default the sql databases created by this extension use a latin-swedish collation, which caused problems with greek characters appearing as question marks (???). I had to manually change the collation of the tables to utf8-general-ci. Then everything worked fine. Not a big deal.
The second problem is that i do not recieve any mail notifications when someone submits a testimonial, probably a thing with my server. I am looking into this trying to figure out why.
Overall, a definite 5 star. Good job!!
