Bluunis is not bad... if you're not in a hurry, check the offers frequently, usually before CNY, they have promotions cheaper than joanna with free 2 touch-ups but i'm not sure how many free touch-ups the other two provides... Also, Bluunis has changed their name from Ultimate Impression and improved their image & reputation because they are now a listed company... so everything has to be in top condition... that was what the people there told me la... I have also good review about Joanna's from friends... so they are all okay but the questions are which environment, price, offer and package suit you?! I think you should go to the beauty centers that you mentioned (all 3 of them), ask them question, look at their store, see which one gives you confident and bargain... cuz when i went to Joanna's, i see "older" and "not so semangat ppl working" eventhough i had a friend who done her eyebrows there... so that affected my decision... then i chose bluunis cuz i went there before and they had promotions on... so take your time to choose...
