We recently moved to Auckland for my project. The signal issue came the biggest problem as no absolutely any signal! Much bigger than non sleeping nights with our kid :D We got spark booster. Did all installation myself, just shop did not offer me tools for setup, but not that big trouble. It works. Covers our house about 120 meters.
Metal super yard gate is fine. I could install it myself. It was funny to follow our kid reaction)) But it is cool, no more headache to leave him around home!
