Catpiano

It works for sure .. just add heel ..  

but I won't call it HOTTEST product of the year la....   

Even 2X yr ago ..  I saw that in some magazine ..   

I am sure even hundreds year ago ..  had similar products ..

However, I have seen lots of them selling in "CUBE" shop in HK ..

Almost bought one .. however ..  all my friends/co workers know how tall I am ..   it is weird if all the sudden add extra 1 in or 2 ga ma ..   

Also, as 布小熊 said ..  especially in Canada, always go to friend's home ..  with SHOES OFF ...   

It is ok to use in HK ...  shoes on all the time ..

Not a bad idea for guys ..  who doesn't wanna be 6' ?  ( ok ...not who is already over 6' ..)

I always wanna be taller ..
