Personally, I love the user interface of Trello, because it's very modern, easy to understand, and it allows you to move one task from stage to stage through its drag and drop functionality.

I also love that you're able to add images, tag your colleagues, and provide updates within any kind of task.

These are the main features and functionalities I enjoy the most out of Trello.

1. It has a very modern-looking interface. 

2. It is easy to use.

3. The product is very intuitive. 

4. We found the setup to be quite simple. 

5. It's not too expensive.

6. Great drop and drag features.

7. Commenting capabilities with auto notifications to team members.

8. Allows filtration of cards basis on key criteria so you can quickly focus on the important ones.

9. Ability to Create checklists for key tasks with assigning of responsibility and due dates 

10. Reminders

11. Analytics with charts 

The solution uses Kanban boards.

The solution is very easy to use.

On the features side, it's very stable.

Since we use several tools, sometimes, we cannot signup daily to check progress. That’s why we appreciate the notification scheme from Trello. Trello will message me the updates. It allows me not to sign up for Trello daily without missing any progress from copywriters.

Another feature that impressed me is the clear Kanban board, as it provides a clear view of to-do tasks, reminding the team not to forget anything. Whenever I see the board, I can rapidly understand the overview of what tasks were done and what should be done. Additionally, colleagues could remind me when I miss any progress.

Mainly it makes it easy to track work and track the status of software. It's great for use in the morning and evening. We can easily track the overall status of projects. 

The user interface is great. I find it very easy to create cards. 

The initial setup is very easy.

It's a stable product.

We can scale the product.

The cost of the solution is reasonable. 

The solution is great for project management. It helps us track the progress of work and tickets. 

It is very easy to deploy the solution.

I have found the solution to be stable.

In general, it works very well. 

I think task management, prioritization, rankings, and collaboration features are useful. It's a really easy tool to enter data, keep track of the tasks and management, and update all of that. It's very straightforward.

Trello is very easy to install and set up. It is also easy to use. Its interface is excellent.

It is stable and quite secure.

The most valuable feature is the fact that I can see everything on one page, like sticky notes, and everything is set up. It's pretty easy to use.

The usability of this solution is its most valuable feature. It offers a great flow of creating a business rule that allows you to just add identifiers and qualifiers. 

I like how user-friendly, visual, and intuitive it is. It doesn't take a lot of time to figure out how to make it work for you.
