I had a very bad opinion about the Vision express optical which is located in Mogappair location. I bought cooler worth Rs.1500/- 2 months before, due to poor quality the frame of the cooler got broke down when I was trying to wear it. I went directly to the shop, I try to fix this issue. They sales person told that there is no guarantee for breakage. Even it gets broken after your immediate purchase. I received such a irresponsible reply from the sales person. Previously I bought cooler for Rs.200/- from other shop and the life time for that ordinary coolers was nearly 1.5 years. I really felt very bad about the poor quality of vision express products. I am going to pass this information to everyone regarding your poor quality.
