E2 Saver, will it really save electricity ?

Yesterday went to Bangsar Villiage and brought a unit of E2 Saver as recommended by a friend. Friend told me it really can save house electicity. He is not selling it, he is using it.

Brought it for RM 359 (usual price), and the sale girl demonstrated using 9 fluorescent lights, and while without the E2 Saver it consume about 1.6 Amp, and it with E2 Saver, the power consumption is 0.5Amp. It is really big different.

You can check on the product itself through their web site which is HERE.
