Is pleased with redesigned Taser (5)
I believe the answer is:
rates
'is pleased' is the definition.
I can't tell whether this defines the answer.
'redesigned taser' is the wordplay.
'redesigned' is an anagram indicator.
'taser' with letters rearranged gives 'RATES'.
'with' is the link.
Can you help me to learn more?
(Other definitions for rates that I've seen before include "Property-based source of local revenue" , "Relative speeds and local taxes" , "Tax paid by businesses to a local authority" , "Evaluates the importance (of something)" , "estimates?" .)
