Hi Rosalie,
I bought my wireless keyboard set up and didn?t do any comparison shopping (it?s not like me to not shop around though.) However, the good thing about Costco store/Costco.com is that they stand behind their products for as long as you own them. Anytime I have returned an item to the store they refunded my money with no questions. After the refund they do ask if there was a problem with the item.
About the set up? There are three items: Keyboard, mouse and a receiver (mouse size.) The receiver plugs into the rear panel of my computer and I have it mounted under my desktop. It works well from that location, too.
The spec?s read that the unit?s will work up to six feet away from the receiver. I just did a test run with the keyboard at fifteen feet away and it works great. Of course fonts would have to be set to thirty six for me to read them at that distance.
The mouse worked well up to a distance of around eight feet. Both the keyboard and mouse are user friendly IMO.
In the beginning one of my concerns was that if I would have any lag time while playing live chat music trivia. It passed the test with zero lag, too. Those folks answer so fast in that trivia room, one second counts big time.
There may be bigger and better units out there, but I think I will hang with this one. Here is the website with additional product data incase you want to read more.
