Joakim Green reviewedMagnifyPush out beautiful website announcements in 10 seconds.
 RecommendedPros: 

Easy to setup, Minimalistic design with clear CTA

Cons: 

Lack of possibility to target pages based on "URL contains"

A more nifty way of promoting things to website visitors. For me Magnify replaces the traditional top bar and some intercom popups (when I rather want a clear CTA instead of chat)

Joakim Green has used this product for one week.
