I presume the first “word” of the name of this product is pronounced to rhyme with the term SNAFU, which is a bit sad because that is not a totally accurate description of my experience (so far) with this product.
I found the instructions confusing, as well as being in much too small type for me to read from the paper. so, scan to PDF and increase the sice of the type that way. I was able to connect via BlueTooth both keyboard and mouse to both the laptops I currently have on my desk; but then the fun that should have started was not as evident as I had hoped.
If I could remember the full detail of what I did in what sequence with what effect … nah, that would be too boring.
I have got to the stage where holding the Fn key down and pressing either the 1 key or the 2 key for about three seconds switches the keyboard connection to either laptop 1 or laptop 2. (No, those are not the names I use, but for the purpose of this post they are more meaningful than, say, Nimoy and Doris.) This gives me the ability, together with the HDMI switch connecting both laptops to a Philips 273V monitor, to easily switch between which laptop is connected to the keyboard and monitor sitting straight in front of me on my desk.
I have abandoned using the mouse, and will continue to use an individual mouse for each laptop. Moving a mouse around is less effort than switching keyboards.
This also means that if I have to quickly prepare to leave, taking either laptop with me, it is easy to also pack the mouse that works with that laptop.
