Has anyone used Transform xtensions recently?

What’s the quality like these days of the Mongolian hair and the Russian hair?

Debating between Transform and Euphoria One. I started using Euphoria One last year but used Transform up until 2017 (and the communication became non existent)

I used to really like the quality of Transforms Mongolian hair, was thinking of trying the Russian hair this time as there’s not much in the price difference
