I have been using for 2 months now. API integration saves a lot of manual effort. But since different exchanges have different support some APIs allow syncing the deposits and withdrawals while others don't. So this leads to negative balances for some coins sometimes. In such cases we will need to add a manual trade entry to balance it out. This seems to be a pain. Other than that I like the tool and have purchased the licence for an year.
