Help with age of Asian teapot

[jtw1313]

If anyone can help with information on this puzzle teapot it is appreciated. Liquid is poured through the hole in the bottom and doesn’t spill through the bottom because of chamber inside

I looked at this for a bit. Never seen or heard of these before.

Kinda cool, but with no markings I have no idea how to determine age.

For what it's worth, you can still buy them on Amazon...
