Review on MOJO Silent Bluetooth Vertical Mouse: Wireless Ergonomic Optical Mouse with Adjustable Sensitivity and Quiet Buttons - Perfect Grip Dual Mode (Bluetooth + 2.4 GHz Wireless) by Chris Shields

This is a very good Bluetooth mouse. On my MacBook, reconnecting after sleep mode is very fast. I've been using the Anker Ergonomic USB Wireless Vertical Mouse in the office and at home for a few years now and this mouse is pretty much the same except the Anker mouse is slightly longer (fills out the lower palm area a bit more) and tiny is slightly thinner ( the Mojo mouse looks a bit thicker). MOJO's surface texture is a bit smoother than Anker's, but I don't feel like it's slippery. Also for use with a Mac, the USB Overdrive app sets botton 4 and 5 to what you want (I set the forward/back shortcuts for them). Best of all, it's Bluetooth, so you no longer have to fiddle with a USB transmitter dongle. Notebook. The key clicks are also quite quiet (not completely silent, but good enough).
