"Rent-a-Wreck" is countable or uncountable?

[Van Khanh]

Hi,

"Rent-a-Wreck" in "have you tried Rent-a-Wreck?" is countable or uncountable? If it's countable noun, how to write it in plural?

Similarly, how to write "a human being" and "a carry-on" in plural?

Thanks

Rent-a-Wreck is a company name, and is countable if, for instance you are speaking of branches: There are Rent-a-Wrecks in all the major cities.

a human being; two human beings

a carry-on; two carry-ons
