Learning Multiple Languages with Pimsleur?

Hi,
Growing up I spoke both Estonian and English. My parents decided to not continue anymore because they feared it would cause confusion for me in school. In highschool I took French and was terrible at it, I started to get a little better with ot when I visited France and later on the tahitian islands. After i started to self teach a little German. I didn’t have much time for it though. Then at work I was introduced to Russian and Arabic, and i really liked it. How is pimsleur working for you? Does it work well?
