Thank you for the guide. The opening was hilarious— a picture says 1000 words.

I wanted to add a note that you need to use a T6 with a very long neck like the one iFixit offers for sale; an ordinary bit with a ~ 1/2” or ~1 cm long head will not be able to reach the two next to the opening to the thumb ball.

I had the same issue as you. My left click got damaged somehow and wouldn’t “return” when I clicked it. Opened it up, took both springs out and compared them. Looks like the left click spring got bent somehow. Straightened it up a bit and put it back in, seems to work perfectly now! I was going to buy a new one, but now I don’t have to. Thanks for the guide and +1 for iFixIt!!!

Hi,

My ergo fell down and I am unable to change the bluetooth selector : it is stuck on « 2 » and my pc does not see he mouse anymore.

Any idea how I could fix this ?

Thanks

hi, are the omron switches of the left and right buttons soldered, or are they interlocking?
