I just got my saber the other day and have to say that I am pretty pleased. The light up and sound effects were really cool. The only thing I'm wondering about is the sound effect gyros. It seems like they do their job 80% of the time, but I've noticed that , especially when held straight up, they are overly sensitive to even very slight movement but don't register at all at times when swung in just one direction. Has anyone else experienced this, or do I have a defective saber?
