The customer service is outstanding! I have called them about 3 times now with questions regarding their services as well as my own issues that they help me solve to make sure it's not something wrong or missing from our end before we launch into creating an account/subscription plan etc.. They are extremely helpful in every way possible!! If there were more features available (like being able to register multiple trademarks at once) then this would be perfect but overall great experience so far. We're using TM engine because of how easy-to use platform allows us all involved within one team - marketing & legal departments alike -- access information quickly when needed without having separate accounts which can become confusing if someone forgets who does what where :) Great tool especially since its FREE compared ot other products out here like oursoundtrademarkchecker.com.
