Followings are uncountable nouns :
Information – you can change it into countable by adding a quantifying noun such as : a piece of information. However, even if you change it into countable, no “s” can be added at the end.
Experience – no “s” can be added at the end.

Followings are countable nouns that can have “s” at the end :
Apparatus - apparatuses
Instrument - instruments
Device – devices

Followings are both countable and uncountable, depending on situation. When they are countable, you can add “s” at the end.
Service - services
Advice - advices
Ability - abilities
Horizon - horizons : should be broaden my horizon (because you only have one horizon).
Horizons – this usually is used as geographical terms. We can have many horizons in the world.
