I bought the Panasonic NR-BY601XS inverter fridge as well. Internally, it's not as fancy as other brands, more utilitarian and functional. The freezer compartment does not have lights, which I found to be peculiar for such a big fridge.

It's very difficult to quantify whether it saves me electricity, I just started using it in my new place.

There's a water container in the fridge section. You take it out and fill it up with water. The water will be piped up into the freezer section to be made into ice cubes, and dispensed automatically into the container.

Added on January 31, 2011, 9:10 pmI'm using Panasonic 601XS. So far it has been fine. I don't have that many stuff to put inside yet, hence I cannot comment on how well it performs under load. My only complaint so far is that the freezer compartment does not have lights! I noticed the same about other Panasonic refrigerators. Very strange.

Sharps and Toshibas have freezer lights in most models.

I put mine in mid temperature settings. I have thermometers inside the fridge to measure temperature, since the fridge doesn't have indicators. I keep my fridge section at about 3-4 C and my freezer section at about -18C. It's good to have thermometers so you know your fridge is working fine. I bought mine from Daiso.

ADJ, how is your freezer drawer? I find mine doesn't glide out as smoothly these days. Maybe the wheels are frozen

I have NR-BY601XS. It doesn't get stuck, just doesn't glide so smoothly. Probably because I don't open the freezer compartment often enough.

Not cold? Just adjust the temperature setting according to your preference. Not cold is very subjective. Ideally, the fridge should be around 4-5C while the freezer should be around -15C. I get that temperature with my settings at mid level. Use a thermometer.

I'm using NR-BY601XS. So far, no issues. Except, maybe I should've gotten a smaller size Freezer drawer is at the bottom, some people do not like that. There's also no light in the freezer.

About a year.
