I like this extension more than other similar ones. But I'm using Tab Reloader extension instead of this one right now because Tab Reloader has 1 very useful feature that is not available in Tab Auto Refresh. The feature is if the tab is active, it won't be reloaded / refreshed. Hopefully, the feature will be added soon.
One good-to-have feature is to allow users to turn off auto refresh for the current tab just by clicking the extension icon like Tab Reloader does.
