Pros:

• Compatible with several time zones, it's great because you can have people from all over the world in the group.
• He has economic plans.
• If the product does not like you can unsubscribe yourself, without having to contact customer service and wait for an answer.

Cons:

• It only allows adding 5 users in the offered plans without additional charges. If you want to add more people to a group, you have to pay extra for each person.

Would I use it?
This product does not attract much attention to me, although I recognize that it is very useful for several people.
