UNRELIABLE: I just spend hours building a Dataset for a Dashboard. Then it startet to crash – and all I did just got deleted. Hours of work just gone. Not once - but 5 times.
SLOW: They have the slowest spreadsheet I have ever seen. It takes 3-4 seconds just to open a field to look up a formula. Saving an entry (formula) also takes 3-4 seconds. That is so frustrating. It takes forever to build something meaningful. I have a fiber connection (>1GB). So it is not the connection.
BUGGY: When you hit save it does not mean that it actually gets saves. Sometimes it just doesn't save and all I did was lost.
LOCK-IN: The Base-Price is $1000 / Month and they only sell subscriptions for an entire year. I guess otherwise they all their customers will leave after a month. With this model they just lock you in for an entire year.
I have written to their support and will update here whether they can fix it or not. Review collected by and hosted on G2.com.
