I am using both Kenwood and Gree.
Both 1 Ton.
I like gree more than Kenwood bcoz Gree got better air throw and cooling.
And gree can work low voltage.
Gree and Hair both are one of the best Chinese Air conditioning brand on the other hand Kenwood is made in Pak by RNI www.RNI.com.pk they claim they got license from kenwood which i highly doubt.
This kenwood is made by chinese parts though the finished product is not bad but still its not a pure UK brand, as they claim it is.
