Very reliable
I'm very happy with this cable. It's well constructed. It's less bulky than the original coiled cable and no-name PS/2 to USB adapter I was using previously. It's also more reliable. It has not dropped any keystrokes in several months of use, an issue that I experienced regularly with the other adapter.
I have two nitpicks.
1. Sometimes, pressing keys does not wake my MacBook Pro from sleep.
2. I preferred the rollover behavior with the other adapter. Specifically, I got one more key of rollover and more predictable output before. For example, with this cable if I hold down the keys "asdfjkl;" on the keyboard, it prints "asdfj" and then on release, it prints "dfjs;". With the old adapter, it prints "asdfjk" when held, then ";" when released.
For my use, the increased reliability more than makes up for these minor shortcomings. I would recommend this cable to anyone with a Model M.
