This is my second keyboard/mouse from Dell. I purchased the same keyboard several years ago and it served me very well. The mouse may look a little flimsy, but it survived MANY HUNDREDS of drops and still functioned without complaint. Eventually the scrolling button quit functioning reliably, so I decided to replace it with the exact same brand and model. I onlly had to replace the keyboard batteries once in several years. The mouse, being frequently used, had to have a new battery every 6-10 months, which seems pretty reasonable.
Keyboard is to small.
The Dell Wireless Keyboard and Mouse work well with my new Alienware m18 R2 laptop. The battery panel at the back of the keyboard is challenging to remove and replace when replacing or checking on the batteries. I have since learned that any degree of keyboard movement can dislodge the inside batteries, interrupting the power source connection, making the keyboard go dead. Therefore, the keyboard must remain as stationary as possible even when turning on and off, where the switch is located on the keyboard side, just above where the number pad is situated.
Easy setup. Works well with my Dell computer.
It started out as a great small portable keyboard with short-throw keys. It typed like a dream. But after 5 weeks (just past the return date), it started to malfunction. It did not transfer the key-press data to the computer properly. I'm back to my old keyboard which works well.
