I just got this deal as part of the Black Friday Day 1 specials, and it's already made me happy with how EASILY my Senja testimonials transferred with absolutely no issue. I just immediately saved around $25/month!
I've tried Bonjoro (which I like but it's $$$$), Feedback Link and a few others over the years, but this one 'SEEMS' to be really great! Although I'm still testing, as it stands, I don't think I'm going to another project.
