I do not recommend; my Macally BTKEY is dead after 3 months of very light use -- could not connect on May 17 (ordered from Amazon on Feb 5, 2011) to a MBPro 15" and a MBAir.Swapped new batteries out twice to no avail. It was OK for the price, and the gap between typing and actual appearance onscreen was a bit annoying, but tolerable.Since this died beyond the Amazon warranty period, Macally says they will replace it (909.230.6888 - fingers crossed) but I will be searching for a more reliable Bluetooth keyboard with 10-key numeric keypad.Willing to take this risk? There are other similar reviews of this product on amazon.I gambled, but lost.Macally BTKey Wireless Bluetooth Keyboard for Mac (White)
