Acronova Nimbie Real Life Experiences

Hi, is this still the best way to rip large cd collections?  I've been using XLD on the macbook but it's painfully slow.  Hoping to find a used Nimbie.  Does DbPoweramp work well with the Nimbie and have good success with metadata and album art?  Interested in hearing real life experiences of ripping (I'm not massively techy) 100 cds to FLAC.  Seems to too good to be true!  Thanks for your time, cheers.
