They have a promote now that if you join before end of March, you get 30% off your membership... Having said that, the hourly rate is crazy high compare against Everyday Badminton and Flying Dragon.
If you pay attention to the photos, the courts look to be pretty close to each other and right up against the walls/windows. Regardless if the mat on concrete floor is BWF approve or not, this place looks super cramped for playing... if the person next to you is a douche players then you run into the chance that your game will be interrupted here and there.
Everyday Badminton is not that great either... they have just recently closed off their original location (thank goodness) and now all members of two locations are cramped into 1 (Hood Rd with decent ceiling height). The padding on the courts there are reasonably good (better than flying dragon imo). But since it shrunk in operation, you can even book a court 2 days ahead... its so annoying when you paid for membership and you can book a court.
