Finally today, I have received the replacement model of the E2 Saver. According to them its an improved model. There was nothing wrong with the old model..anyway they wanted it to be replace...just accepted it lah!
The old unit is on the LEFT.
Finally the replacement E2 saver is plug in. Let see how much $$$ I can save this time.
The old unit will have to be return as part of the replacement agreement.
