My Marathon mouse finally started playing up so needed a replacement, this was the best price i could find, Officeworks at $69 priced matched so I got it for $51.28 with the extra 5% off.
Batteries last for at least a year, probably more like 2 years and I use it for work nearly every day. Not a gaming mouse, comfortable for work though. Comes with the Unifying Receiver as well.
Good price, but delivery kills it. Personally, if I'm paying that, may as well get: https://www.jbhifi.com.au/products/logitech-m720-triathlon-m…
Probably just about the same size, but the triathlon has bluetooth capable of pairing with 3 devices.
