The part has picked our son and it fits well in the space provided. The lateral discs could be higher 1mm, for he walks past a staircase and so the sides of the strips look at the descent completely, to dunes remains a gap. Another weakness is the extremely thin base material - you need at the actual use 4 "lights" (four) screws for attachment, because the base plate otherwise just attaches to the ceiling. Conclusion: There was a request / gift and does not look bad, but the processing does not match the price.
