Very excellent project and very well made...I disagree with the approximate time needed to complete the kit because it is very complex....But very much fun.... I just wonder why your add states that if one has questions or if a part is missing or breaks one can contact you...but there is no phone number and I have tried to contact the site by email and if I get a reply at all it is not for a few weeks ! So my project sits idle until I can somehow hear from the company. On one occasion this forced me to purchase another kit to obtain the parts that I needed. I'm visualizing that this company has a very small office and is severely understaffed! I'm still giving it 5 stars though!
