Who the Symphony Diet 12T 12-Litre Personal Tower Air Cooler is for

Buy it if: Anyone in dry inland heat wanting cooling at roughly a tenth of an air conditioner's running cost.

Who the Atomberg Renesa 1200mm BLDC Smart Ceiling Fan with Remote is for

Buy it if: Anyone running fans long hours, especially where mains voltage sags.

Avoid it if: Anyone using a fan occasionally -- the payback period stretches well beyond the warranty.
