Slack Reviews & Product Details

Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"Straight forward easy to use and intuitive."
What do you like best about Slack?

Found it to be incredibly easy from the get-go I did not use it for any administrative or developer functions but took to it quickly while operating across several teams and found its features incredibly useful.

What do you dislike about Slack?

I did have some teething issues with my account constantly displaying I was offline when I wasn't but believe this was more of a temporary bug. Did not have any other issues besides this.

What problems is Slack solving and how is that benefiting you?

Reducing turnaround on tasks as my manager can see what I was discussing with colleagues as well as a team collectively we could respond to issues when someone was busy or unavailable this was a huge help.

"Slack's All About Channelled Collaboration"
What do you like best about Slack?

I value its ability to channel people, conversations, into a hub where ideas are exchanged, content is shared, decisions are made, objectives are set and eventually achieved. I like its ease of use, its frequency of use by most professionas, its integration with most 3rd party platforms, the reliable customer support it has. Its an outstanding collaboration solution.

What do you dislike about Slack?

Its easy to implement, has very useful features, which make it a very frequently used application. And that popularity is where the downsides begin, ultimately because the App leads to distractions at the workplace. A negative hard to ignore.

What problems is Slack solving and how is that benefiting you?

It solves the challenge of channelling everyone, communication and conversations to a central place where things can get moving fast and easy. Advising on its use and effectiveness is being easily appreciated and accommodated.

"Most Convenient Workspace Collaboration Tool"
What do you like best about Slack?

Easy to use, and easy to track message/threads that require your attention. Easy to sync up with teammates in a huddle session, in which one can share screen and others can draw on host`s screen from remote.

What do you dislike about Slack?

I wish I could customize the UI/theme, like dark theme and bigger font, Aria style. I wish I can integrate with calendar app easily to setup focus time, or no noise time etc.

What problems is Slack solving and how is that benefiting you?

Team collaboration on either text or multi-media format. That helps sync up within the team, better collaboration with remote team members.
