It's a great design, but unfortunately quality control doesn't exist or detect when the welds are weak or fractured. I've purchased 4 of these. The price is right, but 2 of them didn't make it past the 4th cup of tea, and one broke immediately the first time I attempted to use it.

Great. This is my second one. My other one is about 4 years old and still working great. I bought this one for work.

Never used a steeper ball before. I love it!

Works great! I use it daily.

The perfect size to make a personal cup of tea, or fill it to the brim and make a quart. Super easy to use and no tea leaves in my tea!
