Question 1

Being 2.4Ghz, can I have more than one in the same vicinity/room?

Accepted Answer

Yes.

Question 2

Will this unit work with windows 8.1 ?

Accepted Answer

Yes. Works fine with windows 8.1. I installed 8.1 and needed to do nothing else. No workaround or special drivers needed. Just plug in and use.

Question 3

is the receiver included?

Accepted Answer

Yes. It is tiny and there is a place for it to be stored inside the battery compartment.

Question 4

I have limited USB ports.  Can the same receiver simultaneously support both wireless mouse and wireless keyboard (Logitech)?

Accepted Answer

Multiple devices that use the Unified Receiver can share a single receiver.  There is special software to set this up.

Question 5

Is there a wired version of this? I prefer the wired version because I am hooking this up to a desktop and the batteries die out too quickly on the wireless (two kids that never remember to turn off the mouse and two adults who aren't much better). I love this style of trackball with the ball on the thumb side but can never find it wired anymore.

Accepted Answer

There is a wired version, it's the version that this one replaced. It has a red ball instead of a blue one and doesn't have the back/forward buttons. It's been discontinued but you could still find it in some places. You should be able to find it by doing a google search for "Logitech wired trackball".

Question 6

Can you place two of these in close proximity on two separate computers without interfering with each other?

Accepted Answer

I would have to answer yes, I have 3 connected to 3 different computers within 5 feet of each other. There is no interference at all.
I believe they are on different channels so as long as you get different channels you will be fine

Question 7

Since these are refurbished units, is there any sort of guarantee with them?

Accepted Answer

I buy Refurbs all the time an I trust them more than new items since they have all been repaired and tested.  You can send a Refurb back at your own expense and get another one.

Question 8

What does "Refurbished" mean?  I bought two of these and they both have issues.  It feels like there is sand between the ball and the housing.  Turns out there are chunks missing out of the ball. The switches don't always work the first time.  Does anyone know where I can buy new switches and a new ball?

Accepted Answer

No but you can just exchange the mouse for another.  MIne had extra plastic on one of the buttons but I just trimmed it flush with a razor blade.
