I use 2 sets -one for this term, and one for my old serving pc- very useful havng both mice on this desk, without tripping over wires. Bought first Remote desktop in 2000 and corded stuff just does my head in now.
Ive never had any real issues with them, but nothings perfect.
1. The transmission range isnt huge, but good enough
2. Keyboard bateries should be Duracell or any proper long life batts - rechargables are less than useful for the Kb.
3. Mouse batteries - they DO need to be rechargables - they use much more current. However DO spend on the NiMh rechargables - a new set of those lasts me about 3-4 months between charges. Normal NiCd rechargables barely a month before needing charge.
4. For some reason, the third mouse button wont work in TFC if the mouse is plugged into the ps2 port - using the com port adapter is fine.
5. 2 sets work without any problem at all, and dont interfere with each other.
6. Logitech doesnt quibble about broken stuff within guarantee - I spilt Tea in my Kb and they shipped me another one foc.
