I've been internationalizing software since M********* 3 was state of the art, but no other product has yet given me the daily efficiency, quality and support like Sisulizer does. Also, the customers doing translations using the translator version really like the product and doesn't bomb me with support questions. (Editor: competitor's name hidden)"
