Mr. Hoi. A middle aged man.
He knows the important of taking "good bacteria". He has been a long term user of "E" company lactobacillus, quite expensive. He tried only 1 sachet of Master AB 30B Lactobacillus, and it gave him a great impression, as he excreted a lot of faeces which included the coprostasis from his colon. He is really impressed with its effectiveness.
He wife also benefited from Master AB 2in1 Toothpaste. Mrs Hoi has been suffered from sensitive teeth for a long time. She tried all brands available in the market. Once the brand claimed it is good for sensitive teeth, she will sure to buy one to try. Once not effective as claimed, she will leave it for her husband to use. With Master AB toothpaste, she is impressed with it and no more sensitive teeth problem again. She can drink hot & cold drinks as her wish now.
