Trust Wireless Optical Deskset DS-3400D

When i first saw this keyboard i immediately wanted it so when i went in next i bought it, what also attracted me to it was its energy saving technology which lets the mouse run on one battery. But it soon broke, i accidentally knocked it off the desk and the six of the hotkeys were knocked out and so was the space bar, the space bar was pretty easy to fit back in but when i but the hotkeys back in they didn't work so i took them all out and noticed the rubber part which makes the button work was missing. So I think its poor quality that they're not glued onto the button.Again steer clear of trust they dont know how to build these items.Use Logitech or Microsoft, i've NEVER had a problem with there items.
