BookFair in Suntec

Popular organised a bookfair in Suntec City. There is a huge selection of Chinese books. English books were by Harris. We tested the Eye exercise machine to help reduce myopia. The machine works. All 3 boys showed improvement after one exercise. However all the boys guess a lot on the post test. It looks like it may work if we use consistently. I am now seriously considering the purchase of this machine. My only concern is it will become a white elephant as the boys will get tired of it after a while and they do not have the discipline of following through unless it is a computer game.
