I order my first arc keyboard after see one at best buy . I love the small keyboard with large key . also like that there be no number keypad on the side of the keyboard as I do not have a need for it . I like this keyboard so much I order a second one for the office . with regard to the design flaw , both of my keyboard go on the fritz last week -lrb- the second be order one week after the first -rrb- . I have determine that the spring on one of the battery connection be just a bit too large -lrb- true in both keyboard -rrb- . so instead of the battery staying in place thanks to the spring , it push up and out of place and lose the connection . I nearly go crazy on Friday fix the battery every time I sit down to type . we be try a home fix , if that do not work I hope Amazon will allow I to return these .
