G. A. Ballard estimated that ''Druid'' had only about two-thirds the range of her sisters, despite the additional coal that she carried, due to the greater efficiency of the compound expansion engines.

Ballard attributed their poor performance under sail to the drag of the propeller, which could neither be hoisted out of the water, nor feathered. He also attributed their sluggish steering under sail to interference with the flow of water to the rudder by the fixed propeller. The first two ships were re-rigged as barques after their first commission.][

s.[ The 16- calibre 7-inch gun weighed and fired a shell. It was credited with the nominal ability to penetrate armour. After the completion of their first commissions, the two ships were rearmed with a total of fourteen lighter 64-cwt 64-pounder guns, two of which replaced the 7-inch guns as chase guns. ''Thetis'', the last ship completed, was given this armament from the beginning.

Ships
''Druid'' was the last ship to be built at Deptford Dockyard.[ The ship was initially assigned to the Cape of Good Hope Station, where she remained for two years before being transferred to the North America and West Indies Station. ''Druid'' was refitted upon her return home in December 1876, which included rearmament. The ship recommissioned in February 1879 and returned to the North American Station. She returned home in September 1882 and was paid off. ''Druid'' was laid up in the ]Medway

until she was sold for scrap in 1886.
''Briton'' was the first of the trio to be commissioned and was assigned to the East Indies Station in 1871. She remained there for four and a half years, mostly engaged on the suppression of the slave trade. The ship was refitted and rearmed upon her return home and ''Briton'' remained in reserve until recommissioned in 1881 for service on the Cape Station. She was transferred back to the East Indies after two years on the Cape. Her crew was relieved in 1884 by another sent out from Britain and the ship remained on station until she was sold, less her armament, in Bombay in 1887.
The construction of ''Thetis'' followed her sisters after a two-year delay and she was initially assigned to the China Station in 1873. She was transferred to the East Indies after a year on station and returned home in 1877 where she was refitted. Two years later, the ship was assigned to the Pacific Station until she was ordered home in 1883. ''Thetis'' was paid off after her arrival and was sold in 1887.[Ballard, p. 93]
