Summary: Bought this KB to be mounted on a Tripp Lite Rackmount. The screw holes seems to be not align to the Rack holes. It is off by 1 or 2 mm and will not fit. This is strange since the size for Rack is standard height. Try calling Adesso Tech Support and it seems to be non existent.
Summary: The installation into my 19" 42U Rack was a breeze. The Keyboard has a nice feel to it, however others may feel that the pressure is a little on the higher side. I don't feel that way since the key's have a tactile feedback. Can't say much about the build-in touch pad since I don't use it at all.
Summary: This was a low cost tray compared to others I saw, but it does not feel cheap. Install is a snap and the cables in the back to not bunch. The keyboard itself in nice and sturdy and the touch pad worked from the start.
Summary: I purchased this keyboard and shelf for our main rack to connect to our KVM. The included keyboard fits well in the shelf. This shelf does not fit a standard keyboard with a number pad on the right, for reference. Slide actuation is smooth and mounting was easy.
Summary: Not a bit of problems with this unit ... compared with higher priced units. We use it once or twice daily and have not had a bit of problems with the unit. Sturdy and very functional. Pull out ... no problems. Fits in rack perfectly. I should have given it 5 starts ... but I am sorry ...
