Not the cheapest lantern on the market, but certainly the best. Bright, low power consumption and uniformly good radiation characteristics with sharp separation of the sectors. In addition very stably built. This winter I had demolished the (self-made) base at 60 knots of wind force and corresponding lake, and the lantern was thundering for two days hanging on the cable against the top of the mast until I could fix it again in the next port. The paint is a bit off, but the case is intact and it still works flawlessly.
