Update, June 2013:
I have a total of 855 miles on three different bicycles with these shifters. Including rain and snow. Except for initial problems listed below they have operated perfectly. I have a 70 year old neighbor friend who just purchased a bicycle with these shifters and everything is perfect and she is very happy with them compared to twist grip shifters.

I would buy these again and I would recommend these to a friend, just do not to hesitate to return these if they have initial quality control problems.

Original review, Sept 2012:
I purchased 4 different bikes this Summer all had this shifter. Two of the bikes shift great and the other two had real bad shifting with the front derailleur. I thought maybe it was because of the cheap no name derailuer. In frustration in trying to get the shifting properly adjusted, I took off the covers to this shifter. Inside I found lots of aluminum metal shavings scraped off from where the bottom of the thumb shifter rides. The escapement mechanism was full of burrs so I went in with gunsmith / jewelers files and a small machinists scraper to smooth the cog surfaces out. Then I touched the surfaces up with Park Tools Poly lube grease.

This makes shifting smoother. Must have slipped past quality control. This being Shimano, I am very disappointed.

I would not discourage anyone from purchasing this shifter as I love riding with them when they are working properly.

It was a bit frustrating to install. The instructions sent with it were pretty useless, being a generic sheet that covers the entire drivetrain of a bike from the shifters to the derailers, but without enough detail of this specific part. It would have been a lot easier to deal with if it had come with a brake cable. But I got it installed, and it works fine.

Much the same review as the other side, middle of the road, the problem is supply does not last so get them when you can or they will run out and you will be waiting.
