If you want notifications so unobtrusive that you don't see them half the time, this add on is for you. If you want notifications you actually notice, try something else.

It actually uses notifications instead of sounds and that is great. Timer is slightly off and seems a bit longer than it should be but I don't mind.

No longer seems to work. I can select the alert period but alerts never come

Should have a flexibility to add the break length and customize the break timings also
