[Chill Names]

I have never used the service of premium features of Sedo and Afternic. (Mls-dls)
I wanted to ask you your experience on theese platforms sedo-afternic ,using premium features:

1. Did you increase your sales paying por mls-dls premium service?
2. Do you suggest to use it for all domains?

Let me know your best opinion.
