I don't know about other's experience with this institute, but i had a ugly experience with the one in janakpuri.
First they will lure you and mesmerize you to join the institute.(which one will do with all these good reviews).THE AMBIENCE ITSELF IS SOO TACKY.
But there after you will get careless treatment.The trainer and the quality promised will never be entertained.And they will go u limit to ask you to pay the payment within days.
I paid 1000 for one class.SO, better your choice.....
