    Posted by Lee on 20th Mar 2021

    I received my jammer and it even arrived 2 days earlier than I expected. Tested it out and work better than I expected. The fan is a little louder than I thought but over all I am very happy with it.
    I also emailed Taylor about a couple of questions and he got right back with me on the same day. Great costumer service. Thank you. Would definitely buy again."
