The product is excellent, but they claim to be "GDPR-compliant" when they are not.
They obtained access to client emails stored in my clients' accounts (emails are personal information according to the GDPR) and sent promotional emails to my clients. I pointed that out to Manny, he wrote it will not happen again, but it did. Also, it took them over 2 months and several reminders to prepare a DPA, which they never provided in the end, probably because they are not GDPR-compliant after all. I cannot risk getting fined for breaching the GDPR.
If you don't care about privacy, go for it! The product itself is great.
