Slight Modification to Hario Buono Kettle

When I first bought the Hario Buono Kettle, I was slightly annoyed that the small holes in the kettle top were too small to place a thermometer in. Here in Burma there are plenty of small mom-and-pop hardware shops that can accomplish just about any task thrown at them, so I headed over to one on my street and told them I wanted one of the holes to be made large enough to slide a digital thermometer into. I had no idea how they would go about doing it, but within 30 seconds of looking at it, they told me it was as simple as using a drill bit to make one of the holes larger.

Here is the result. I'm now able to keep track of the water temperature throughout the entire brew process. I'm happy to report that this Hario kettle does a fantastic job in retaining heat. Over the course of a 3 minute brew, for example, the water temperature decreases by only 1 degree Celsius.
