RF mice may be slightly more responsive and are much easier to set up. All you need to do is simply plug in the dongle and your mouse will be connected. The only downside to this is that you lose one of your USB ports which will now be occupied all the time the mouse is in use. Bluetooth mice, on the other hand, are more convenient and can easily be shared among several computers. In simple terms, a Bluetooth mouse connects via your computer’s Bluetooth signal. The downside is that configuring one takes you a few steps. Whenever your device is boots or wakes, you might need to wait for the mouse to get activated. Also, an RF mouse can only connect to one device at a time. A Bluetooth mouse, on the other hand, provides interoperability with multiple devices as long as they have Bluetooth support and are compatible with the mouse.

No. The refrigerator with the ice maker in the freezer can only make cubed ice. But we are thrilled with the refrigerator and wouldn't trade it even though in the past we did have one that made crushed ice. It had an external ice maker and I don't miss the mess.

No. There is no setting for chopped ice if you are talking about the refrigerator where the dispenser is actually in the freezer. It only makes cubed ice. But I LOVE, LOVE, LOVE it and wouldn't trade it for anything. I had a refrigerator that had external water, ice, crushed ice dispenser on the outside and the outside of the refrigerator was always a mess including finding ice cubes and drinks on the floor from some people filling their drinks before getting ice. I was so done with that. And we don't miss the crushed ice at all. Hope this helps!

If you search the internet and type in the exact question above; you'll find all sorts of answers to your question or any question for that matters. Doing a little research; I read where you should stick with white vinegar or dishwashing liquid. There are some UTUBE Videos out there but if it sounds risky; I wouldn't try it.
