Xfinity's product tour
Xfinity uses tooltips and hotspots to direct user attention to different features on the screen during the onboarding experience. Here's a video screenshot of what it looks like:
What we like: each tooltip is informative and gives a short description of the purpose and use-case of the various features.
What we're not crazy about: firstly, 8 tooltips is a lot. Without a progress bar, this product tour starts to feel like a burden for the user with no apparent end in sight. Secondly, this is a very show-oriented product tour that doesn't really engage the user in the product.
