Our Clients Say About Us

we’re proud to recieve every customer review, read our latest customer reviews.

I wanted to send a personal mail to say how impressed I am with the approach DRO have shown since my visit some months ago. The team here tell me weekly that yourselves are communicating with clear precise detail and delivery dates that are achievable. The NCRs are reducing and the general feeling is that DRO are now displaying exactly what I always felt you could do. My message is keep up the good work and thank you for showing a positive attitude and willingness to work with us through the initial issues we had. Keep up the great work.

Client Review

Our main focus has always been OTD, and to say when we first started the expediting of these parts the delivery was confirmed at the end of August. Everyone has worked together to pull this back in line and we have exceeded all expectations and actually delivered way ahead of schedule. There have been numerous emails on the back of the below from the senior management, congratulating everyone involved, so it’s only fair that this recognition is passed on to the supplier who made this happen in the first place. It is great to know we can depend on our key suppliers whom we have developed an excellent working relationship with and its testament to you all for the support you continue to show in meeting (and exceeding) the milestones we set. This is a fabulous achievement
