I hesitated because the previous response, but I'm glad I went with my gut.
In short good and recommended
After requesting more detailed documentation and tutorial, i've got answer from developer, that it all will be implemented in new, upcoming version in couple of weeks.
Five weeks is passed, there is no new version. I contacted developer again regarding new version, and this time he didn't say any words about the new version, only directed me to very poor, old help section on their site.
I thought it's not fair to promise new version, and not keeping this promise. So i contacted this developer again, but this time trough PayPal. Right after that this developer blocked my IP, so now i can't even access their website.
Overall what i want to say, is that this extension lacks documentation, and i had not so pleasant experience with the developer of this extension.
Will be glad to write a new review if developer will provide detailed documentation or new version (as promised)
(I have few years experience with Joomla, and easily working with a lot of advanced extensions)
