We bought Symphony Sumo Jr. Aircooler on past summer.Though Symphony is a Well Known Big company but this cooler is worse by them.We faced many issues on it till now.
Its not efficient to cool a little room even.Very poor cooling capacity.
It takes a lot of time to start.And stops sometime during working.Very disappointing.
There is an annoying noise all time during running it.It does make concentrate on any work.
This cooler is Large enough & Heavy weighted to move compared to other coolers.
I think its not a good choice but ee did the wrong.So Dont buy it.I’ll not suggest it to any one.Neither Durable nor Reliable.
