Topaz may make good products, but their "customer service" is terrible. I recently attempted to purchase AI Gigapixel, but their site rejected my credit card. I knew there was nothing wrong with the card, but I called the card company and verified it just to be sure. Topaz doesn't have a support telephone number (or any phone number that I could find for that matter), so I sent them a "help" e-mail. I described that I wanted to purchase their product, and that their website incorrectly rejected my credit card (I wanted to use my business credit card only). It's been a week now with no reply. Very frustrating experience!
