- (2025-08-10) Shunya Abe: I was using Event Merge before but i did not like it much. But I love this rainbow approach. Thank you building this!
- (2025-05-23) Mel Mor (Melanie Morris): This app is amazing!!!! I was very annoyed and frustrated with the duplicate events showing from shared calendars!!! I spent a lot of time deleting, combining, and organizing events! Merge duplicates Google Calendar events is a timesaver! Thank you for creating this essential timesaving app!
- (2025-05-13) Erika Flores: Was great but stopped working--any tips?
- (2025-03-07) Alex Jacobson: Thank you for all your work, it looks and works great. I do, however, second the review about dark mode. If there could be some kind of option toggle to set/disable a different weekend color, that would be great, please. For now, I just unchecked the "Show weekends" option in the Google Calendar settings. I'll submit the feature request on GitHub.
- (2025-03-06) Travis Wieser: Please remove the background color on the weekend days. It makes dark mode unusable.
- (2024-12-23) miffy: best event merge extension for sure, but is there any way to not have the blue background behind the weekends. its really ugly to me, and clashes heavily with my event colours. especially when i already have an extension that shades days, but its hidden underneath this extensions weekend colour.
- (2024-11-04) Cheryl Hammond: Seriously don't know how I'd live without this extension - it turns a stressfully-cluttered calendar into a work of art, with lovely ombre effect. Team was super responsive when I posted an issue on GitHub. Grateful for y'all's work!
- (2024-07-24) ThaÃs Gouveia Osti: This is excellent! I've been using it for a while now and it is a life saver, helps with duplication clutter a lot! <3
- (2024-05-14) Midge Stocker: Visually great, but I found that some merged events just disappear from my calendar altogether instead of being merged. This happens when I use a custom view set to 2 weeks, which is my preferred view.
- (2023-04-11) Eunice Hung: The first calendar merge extension that doesn't leave a blank space where two events were merged into one, pushing later events further down.

- (2022-11-23) Mathias Böhmer: Great to merge calendar events! Thanks a lot, solved the painful sliding-bug at "Gradient Merge". But, this extension is very hard to find. Found it only through the comments in "Gradient Merge". Maybe you want to think about a more describing name and description. Nobody googles for "rainbow" or "surf", when wanting to merge calendar events

- (2022-09-29) Cheryl Hammond: I have literally like a dozen color-coded calendars for different organizations and this extension not only helps me keep them well-organized, it also makes them pretty!
- (2021-09-11) Zachary Wiles: Perfect calendar enhancement! Exactly what I need for the messy display of shared calendars on Google Calendar! So much cleaner now! Also, I have my week set to start on Monday now so I can think of a weekend as one block and see it that way. This extension adds background colors to weekend days which helps my brain more easily make the adjustment from the old Sunday-first view and there is no more confusion.
