It so happens that the scroll wheel of my five years old Logitech MX Master Wireless Mouse spoiled just a few days before one of the greatest sale day, the Singles Day (11/11).
Technically, it is not spoiled, but the scroll wheel is forever in free-spinning mode, aka the clicky/ratcheting is not working when the SmartShift button is being pressed. There is an article on how to fix it, but it seems the fix is not permanent. It will come back within a month, probably due to the spring being loose due to its age. You will need to tear the mouse’s feet to access the screws every time you fix it.
I bought the Logitech MX Master 3 Wireless Mouse from Lazada during its Online Tech Show. The recommended retail price of the mouse is S$169. After the 8% discount by Logitech and deducting Lazada’s S$12 voucher, HSBC S$20 voucher, I ended up paying just S$123.48. Shipping is free as I shipped it to a Ninja Point.
After purchasing my first Logitech MX Master back in April 2017, I went ahead to buy two more Logitech MX Master mice in White and Navy when Amazon is having a sale in May 2017.
I sold the Navy and my White spoiled after nine months probably due to bad luck. My first Logitech MX Master still works perfectly in the office. Since I bought it from Amazon, there is no local warranty here in Singapore.
