Credit Enrollment Question.

Hello all, I’ve been using Sezzle a lot lately as I have “Anywhere” and it’s the main card I use now wherever Visa is accepted, I’ve had zero problems with Sezzle so far & have been using it for months (I personally love it). My question is, have any of you gone through with the Credit Enrollment option? Is it safe? Pro’s cons? I have a very good history with Sezzle and do believe it could help my credit. Just wanted to hear others experiences first!
