What Slack Does Well

A lot of users commended its free version for being robust and having all the essential messaging functionalities. Excellent integration capability was also cited consistently.
“It is excellent for teamwork. It allows integrations with other apps, which is incredible. I can keep all my messages and information in a shared but organized way. Team conversations are excellent. The communication and the dynamics of the working group have improved because of Slack.”

What Slack Does Not Do Well
Users who gave Slack a negative review suggested improving its voice call capability to be more similar to other VoIP solutions. Some users also complained about sporadic system glitches and the unreliability of the video chat feature.
“The biggest downside is that it’s not a total Skype replacement due to the lack of VoIP. My company is very married to Skype because of its VoIP functionality, despite the fact that Skype consistently fails for us as an overall communication tool.”
