We have a bunch of Garhauer stuff and on the whole we are very happy with it but there are a few annoyances.
1. The rigid boomvang is great - no issues
2. The Davits and the solar panel supports are good although a few corroding set screws are annoying and could have been easily avoided
3. The 'sliding' Genoa cars are a disappointment. They do not move easily (or at all) under load. The reason is pretty obvious. Ball races need to be recirculating. A straight run of ball bearings does not work.
4. A bunch of blocks etc. seem to be well made and working fine so far.
