    False advertising
  

*by G***A on Reviewed in Canada on 2 November 2020*

It supposed to be a 12 pack as stated in the product description , instead I've received only one piece .When you order all the kit parts and count them so you have as many as you need of each it's very frustrating to get one component of the whole kit less quantity than you're expecting . Now more delays in fixing the issues because I have to wait another fey days or weeks to get it .
