The only reason I registered for an account on Joomla's site was I simply had to write a glowing review of Andrey's extension and customer service. I only wish there was a 10 star option labeled something like "out of this world." This is the first time in the last 2 years that I've felt forced to drop everything to sit down and write a review of any product I've bought.
It worked perfectly out of the box and I was able get it up and running in 15 minutes (I'm not exaggerating!) The number of options and different ways you can filter the results is astounding. It really does take K2 to another level. If you are going to use any K2 extra fields in your site, buying this extension is absolutely necessary.
The only problem I had initially was the extra fields weren't sorted alphabetically/numerically, they were listed in the order you had added the values. As most of the other reviews have mentioned, Andrey replied quickly. I'll share his very easy to implement solution as I haven't seen it noted anywhere else and I expect most users will want their extra field values sorted.
----I submitted this review with the code, but it was rejected. If you look at Andrey's reviews on the K2 site I posted it there. -----
Later I decided I wanted to add a new feature to my searches which it couldn't handle out of the box. I knew it would be extremely difficult to make work. Before I bothered Andrey I searched for a solution, unsuccessfully, for hours over the course of a couple days. Entirely stumped, I asked Andrey if he could help. Again he responded within hours. I'm not exactly sure how many hours he spent trying to create a custom solution, but from the number of emails we exchanged and the amount of time he was logged in to my site, I'm betting it was at least 10. To my astonishment, he didn't stop after he realized how much time it would take and ask to be paid for his time. Considering I had only paid him the $30 purchase price and I was trying to add a new feature, not just basic customization, I can't think of any other company or individual who wouldn't have, justifiably, expected additional compensation. Andrey, thanks again for your incredible generosity!
Even though I don't need another license at the moment, I'm buying another for future use just to show my gratitude.
Well, I think I've said my piece. ;-)
