This is hilarious, because I broke my teapot the EXACT same way that another reviewer broke theirs! I was always very careful with my glass teapot, because obviously you have to be- since it is glass. However, one night, my hand slipped; I dropped the LID into the teapot and it cracked the bottom of the teapot, right in the centre! :( The lid surprisingly came out with no damage... At least I got almost 1 year use out of it.
As long as you are very careful with this teapot, it will probably last you a long time! Some people might wonder if it is worth it to buy this, since it may seem like extra work to have to be so careful. In reality, I don't think it's too much extra trouble. Having a glass teapot, that you can boil your water in, really improves the flavour of your tea- because there are no impurities or weird things coming off from any metal or plastics that are in some other, more typical kettles.
This kettle is also very beautiful in shape. It is fun and pleasant to use, and does a great job at boiling water. For me, the price also can't be beat; I think it's a great price for a nice product like this! Like I said, it is great - as long as you take care not to break it!
