No customer service line, no prompt response to messages. Write it section should be expanded. No mention of punctuation or how to apply such. Useless, in my view, without more help. Pimsleur does a better job of making reviewing a lesson(s) possible. I gave high marks on the satisfaction score because I like the way several parts of the module are taught, better than Pimsleur, I think. Price was also great. I think Pimsleur is too expensive, but their customer service is much, much better than Rocket.
