Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"The most valuable feature is the screen sharing, which works well."
"The portal is at its best version now."
"Tasks and team huddles are the most valuable features of Slack."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
"The product is easy to use."
"Slack offers several valuable features. Firstly, they have a message deletion feature, which is now available in other software as well, but Slack was the one who introduced it in enterprise solutions."
"The product has the ability to scale."
"The solution makes it easy to create groups, share documents, and communicate."
 

Cons

"The audio calling service needs to improve its quality."
"There were some additional features coming up, as they informed us through email. But we didn't get any update on them."

"When someone responds to my message in Slack, a new window opens. There should be an option to roll down the answers."
"Slack's interface is not simple for me. It's not a user-friendly interface"
