I did the self defense class (INPOWER). Class started 10 minutes late because they were waiting for 2 students (who never showed up and who couldn't be reached). So basically they wasted classroom time of the 11 students who bothered to show up on time. Not a great start. The guy, Mike, was nice. However, his presentation skills for the theoretical part were really bad. Furthermore, the presentation had zero structure, it was just a jumping from slide to slide, videos wouldnt play, and the physiology aspect was comically basic (and at times wrong). The practical aspect was a bit better and interesting but still very basic. I learned a few things (hence the 2 stars) but I could have learned a lot more in 2 hours.
For what they charge at full price, it was definitely inadequate and even with a Groupon, it was not worth the money. Again, the guy was very nice, so nothing personal!
