What part is it and for what vehicle?
Standard was one of the very best at one time but now have gone down the same road as many others, mediocre consumer grade stuff in many cases.
A lot of stuff made in China or elsewhere in third world Asia, some good some not. Stay well clear of their T series (green box), this is real junk.
Buy their standard red box or Blue Streak (rare these days in the US) only if you buy SMP products.
Some of their better parts for Asian cars are the Intermotor (usually OEM brand e.g. Hitachi, Panasonic, etc or other Japanese).
BWD (previously Borg Warner) is also SMP and sold at a lower price, same exact part different box most of the time.
Beck/Arnley and Airtex/Wells have been pretty good, they are repackagers but the parts i have gotten have been OEM or major brand including Intermotor, Delphi, Hitachi, etc.
