Please remember that kendamas take time to "wear in" - both the wood and the paint. It can take at least a month of regular play with a kendama before you really get the feel for it. So if you do post a review of a kendama, make sure to say how long you have been playing with it.
(E.G. "These are just my initial thoughts after a few days with my new Ozora....")
Also, remember that reviews are just opinions, so one person's experience of a kendama may be different to another's... or to yours!
That said - post away with your thoughts on the different models!
I like to think that I'm reasonably cautious when I do my reviews for Mirek. Perhaps I should add a disclaimer and the beginning, stating that I test them from new. I'll be doing two more reviews quite soon, so I'll try and keep that in mind. Cheers.
