Hi,
It's about time I equipped our flat with some smoke detectors and other fire safety equipment (there is sometimes a light burning smell coming from near a light fixture, but nothing visable/easy to fix!). Reading old threads, I saw a reference to this fire safety shop "Index" in Wan Chai: http://www.fire.hk/, which seems like a reliable place nearby to get these things.
Does anyone know how their prices are, though? Are they unreasonable high? I won't be going back to the states anytime soon for these things and I'm not particularly keen to go to Mong Kok or Sham Shui Po. Please let me know, though, if there are any other shops that might have good prices and reliable equipment.
