Amazon bait and switch! Logitech M570

List of problems I found with this purchase not just the item itself:
1. link to the item in my order confirmation email (Jan 2019) is pointing out apparently to the same item “Logitech M570” but it’s not!
– the seller is different (at the time it was sold by “Online Saving” but now is pointing to “Logitech Store”
– the product number is different, mine is 810-001807 not advertised 910-001882.
– basically “Logitech M570” does not equal “Logitech M570”
– it says the item is available since 2010 but this is not true since they sell multiple generations of these mice under the same name, clever isn’t?

The story about the item itself.
Bought this mouse Jan 2019. Double click issue started in 2020. Not sure when exactly but it’s over 6 months now. Was not suspecting this pretty new trackball mouse but system settings (OS software updates weekly – things can turn bad here or there) but had no time to investigate which settings can cause that click behaviour because I never touch the mouse settings – always stick to defaults.
Initially it was on/off issue then the issue persisted.
I looked on the web and found that people experience the same problem with this model but then after some digging I found that the mouse that was sold to me has a crappy micro switches which fail pretty quickly.
Make sure to check the product number after receiving the item because they sell old crap hoping people won’t notice.
I think people who sell these mice also sell cars.

This is an easy solution by Rob Shafer:

I just disassembled the top (5 screws… one under the battery positioning sticker and 2 under the center front rubber foot and right side rubber foot) and put one drop of WD40 on each of the micro switches… don’t spray it on the switches obviously. Spray a puddle on the bench and use a small screwdriver or similar to pick up some of the WD40. Place it on the button for the switch then depress the button allow the WD40 to enter the switch. Cycle the switch multiple times to work the WD40 into each switch. A nice solid click will return to the switches and all of the missed clicks or double clicks are gone.

Replace the switches themselves. Guide thanks to Gary Quiring
