Question: what is the diameter of the spout opening?
Document: I love the fact that the opening at the top is just wide enough for me to get my hand in there to wipe it clean. And the handle folds over so that it can be filled with water without making a mess. My favorite part about it, though, is the fact that the spout cover flips open so you don't have to hold it. When you're done pouring, just flip it back closed again. This one is a five star product, and the price point can't be beat.
the teakettle is small and sturdy with a loud whistle, i just wish it had a bigger opening so it would be easier to scrub, but I only boil water in it anyway.
This kittle is not bad for it's price. Cons is it is very hard to clean sunce the opening is very small. It says stainless steel but you can see some areas already stained but that's what you get for the price. Good for camping.
It worked fine this morning and seems like it will do the job. Very light and a small diameter so it's best for a single person. The one thing that struck me was how the handle folds down, I guess to make it easier to fill it with water.
Whistle-lid (the lid on the spout) fell off after about 2 months. Granted this was priced cheaply, but I didn't expect it to fall apart.
I purchased this at a local Target for occasional use. Not only does the handle can get too hot to touch, requiring an oven mit to pour the water but the plastic melted off of the spout.
This kettle, is great! It is just the right size for the small burner, and is very sturdy. I open the spout from the top, & behind, and have yet to get an injury. I highly recommend this item.
For those that are not sure how large it is, this is a mini kettle. It's a half the size than what would be a regular kettle. Other than the discoloration the item still does what it is supposed to do, and I have not had any issues with the black handle or spout causing issues.
My only gripe and it's a minor one is the low capacity. Maybe I was expecting a little more. The kettle can only be filled about 2/3 of the way before it leaks out of the spout. Otherwise it's great! I have heated alot of water for tea and cocoa!
Great idea, but bad quality, got it for Christmas holidays and now ready to recycle it. It is leaking at the bottom, welding done poorly and it will be going to trush. Spout cover is not tight enough and water spilling all over during boiling. Do not waist your money here.
Answer: it's 1 1/4 inches
