I wanted a track light kit with a bendable rail for over the dining room table. Checked with big box stores and only saw plastic junk.
The Kovacs kit is a nicely designed and solidly built. The parts that look like brushed nickel in the photos are the real deal, not plastic.
I wanted to bend the rail into an ellipse, with a major axis of 48" and a minor axis of 26". The minimum radius is about 9.5". I was able to bend the rail to this shape by carefully forming it around 3 different round objects. You do have to make sure the rail is supported when you bend it so that it doesn't kink. The rail can also be cut to length, but I didn't need to do that.
I wanted to be able to hang some strands of glass beads from the heads, so I attached the stand-offs to the ceiling with toggle bolts, instead of the drywall anchors that are included in the kit. The top of the rail ends up being 4" below the ceiling.
Installation was straight-forward. Though I haven't installed the dimmer yet, no problems. The product looks great - the lighting is brighter than expected. The drawback is the high amount of heat produced - a dimmer should cool it off when full power isn't necessary.
