If i could give zero stars
If i could give zero stars, I would. The patterns will not save, and the switch is not easy-to-use. They are cheaper LCM flasher modules out there that are easier to use, and offer more patterns.

Thank you for your review. I am sorry to hear that you are not happy with your Z-Flash. I am not sure what you mean by "patterns will not save" since there is no software available to make custom patterns for the Z-Flash LCM Plugin Flasher For GM. The patterns are built in. I will have one of our customer service team members contact you for assistance.
