We use mircobase to manage our employees' attendance, it's very easy and intuitive interface with all features we need in one place! It also allows us send emails directly from inside so no more time wasted sending them through other means like excel files or google sheets etc..
sometimes you get error messages but they are usually simple enough fixes that can be done online without having any tech support person at your side - great if this happens during business hours when someone else could help otherwise not such an issue!! nothing really as far I know everything works perfectly fine except maybe some minor bugs here n there which have been fixed already since its launch date (over 3 years ago). If i had something nice about using their product would probably say "it has helped me reduce my workload" because now instead of managing multiple spreadsheets manually each day/week /monthly what used too much manual labour before just doing once daily.
