I have used Eno for about 3 years now. After having credit cards stolen in the past and developing paranoia about enter my credit card information online, Eno seemed like a good alternative. So far, it continues to work extremely well for me. 3 websites that I used were compromised and within seconds I was able to shut those virtual numbers down without interrupting my main account. Eno sends me text alerts whenever there is something questionable, and I can react in real time if necessary. I have had some issues with the app after some updates have occurred to my computer, however, I have always been able to get quick resolution to my issues. (Note here, Pre-COVID 19) All in all, I am very happy with Eno.
