In terms of reliability, I haven't heard about any recommendations from the clients who use the tool. I think it is better for a regular user of Zoom to speak about the product since only such a person can provide more details regarding whether the tool is good or bad. If you want to know about Zoom from my perspective, I think that I can't give you much information related to the solution.
When I join Zoom meetings, especially the external ones, I feel that the video quality is okay. I rate the tool's video quality a seven and a half out of ten when compared to Webex.
Though I haven't thought about the sound quality offered by Zoom, I feel it is okay.
During multiple conference calls, Zoom, Microsoft Teams, and Webex post different limitations in terms of screen sharing and presentation capabilities.
I would recommend that instead of Zoom, others can also use Webex and Microsoft Teams.
I know that nowadays, Zoom is securing their communication in the area of conferencing, specifically video conferencing.
Others can use Zoom if they want to use it.
I rate the tool a seven and a half out of ten.
