Trim tabs
You can't give a general thumbs-up or thumbs-down rating. The product itself is of okay quality, so thumbs up, but it also has flaws, so thumbs down. Regarding the flaws:
The upper brackets with the cable openings for the cylinders didn't fit the cylinders. They were a good 2 mm too narrow. I had to file and sand down the area on the cylinders with the screw hole, which needs to fit, in my workshop. It's unacceptable that something like that doesn't fit. Furthermore, at this price, a few more meters of cable would certainly have been included. The system with the plug connections is very good, but I had to splice in some additional cable to reach the control panel at the helm because the supplied and pre-wired cables were far too short.
