I received my repaired shifter a couple of days ago and yesterday I installed it back on my Cannondale Lefty 3.
What a PITA.
The app, which is needed for the install, does not work well with an iphone. It took many, many tries to get the app on the phone to connect with the shifter.
Then, when trying to dial in the gears the shifter did some really weird things. Each time I shifted up, using the app, to the next gear the Archer shifter dropped the chain back down to the smallest cog. I then had to, using the micro adjustment button on the app, move the shifter back up to the correct gear.
I had to do this 11 times!
After I finally dialled in the gears I mistakenly turned off the app before pairing the remote to the main shifter. When I realized what I'd done I tried get the app to recognized the shifter again......no dice.
After a dozen tries, including deleting and re-installing the app I gave up and went back to my computer to write Archer a less than complementary email.
After having my coffee I went back out and tried connecting the app the the shifter again and to my relief it worked. I was then able to pair the remote to the shifter.
Happy days......not so fast.
When using the remote the shifter would sometimes move two gears when I only pressed the remote button once. I used the micro button on the remote to move the chain back up to where is should have been.
I had to do this multiple times.
I finally got everything dialled in, but I haven't taken the bike for a ride yet to see if everything works properly on the road.
I definitely would not recommend an Archer shifter to anyone who only has access to an iPhone (like me). The app does not work well with an iPhone....at all.
Archer needs to fix their app ASAP.
I still like this product, but given what I've gone through I wouldn't buy it again. I know that others on this thread have had zero problems with their Archer shifter, but that isn't the case for me.
