I have to commended Paradigit on a faultless service. I returned a 2gb Ssd & they credited me so i could replace it with a 4gb. All was very smooth & returns were made very simple. If i was to make a recommendation it would be with the time taken & tracking of both returns & replacement delivery it seems very slow compared to others. But nevertheless i was happy that i had been able without stress to do this.
