I was impressed how good it looked without doing any sort of modifications at all!
I had a question concerning a possible future add on and the support was quick and helpful. That is huge.
I highly suggest you give it a try for yourself. Great features and solid support.
Note: I quickly rushed through the demo and didn't notice it was not for k2. It would have been nice if it was pointed out though.
Thank you for your feedback but I want to tell our extension DOES work with K2 and we tested it carefully.
If it does not work for you, you can ask us for support. Also, we will refund the money if my customers are not satisfied 100%.
