I am now finishing week two with my new Dual Kanagaroo and couldn't be happier! After sitting and slouching at my computer now for 24 years for 8+ hours a day my body was starting to break down. I thought there might be a transition period to get used to standing all day but I've been doing exactly that since the Kangaroo arrived and couldn't be happier with the setup. Thanks to you for making this and to my boss for investing in this for me! Thumbs up all the way around-and even to be made in the USA, too! Double thumbs up!!
