The best review of DHL can be found at Unishippers.com where a study of over 14,000 shipments is discussed. LiveScience.com also covers a study of shipments with the major companies, though not nearly as many packages were sent. Associated Content does not evaluate shipments but does provide a thorough comparison of DHL and other major shipping companies.
Reviewers are disappointed that DHL is shutting down U.S. operations in 2009, claiming that the move will hurt competition. The company, known as a low-price carrier, will continue to offer international shipments to and from the United States, however. Experts say that DHL is the leader in international shipping with better connections in some remote locations and the only provider who can ship to North Korea and Cuba. Though the United States Postal Service is also well connected internationally, they hand all packages off to the local postal service, which can be a disadvantage when the local system is ineffective. Reviewers are also impressed with DHL's detailed tracking, though they claim that it is not quite as detailed as that of FedEx. One downside is that it can be harder to find a DHL drop-off location, especially if you live in a small town.
In a 2006 PA Consulting Group study of overnight deliveries, DHL is found to be just behind UPS in reliability. DHL rates 90.66 percent reliable while UPS and FedEx rate 90.83 and 88.02 percent respectively. DHL is the exclusive sponsor of this study.
