Great Product, and Great Service. You'll never be forgotten with these guys.
Almost every extension I've purchased or downloaded so far (and my theme, especially), for Magento has come with outrageously terrible support and nonchalant attitudes towards any issues I've had. Even with my offers to pay them, I've gone ignored.
That's why the timely, helpful, fast-results assistance from Amasty really shocked me. I had not expected anyone to really make the effort to deal with my issue, much less get it accomplished the first time around. And each time I've come back to them they've been incredibly amiable and have given me results each time.
No only is this product amazing (I have SO MANY new capabilities with my navigation and the ability to add color images is really neat!), but it does just what it's advertised to do without any extra work on your part, and that's really a blessing these days. I especially make use of being able to make my attribute options double columns and turning my color options into small thumnails. Clean and professional looking, to say the least.
In a nutshell, I highly recommend this product. Great support for a great product. Very happy and don't regret the cost at all. :)
