I purchased this as a birthday gift for my boss. I was a little perplexed with what to buy him. He had recently been diagnosed with Parkinson Disease and after reading up on this nasty disease, they recommended brain stimulating puzzles which also helps with dexterity. I called Craighill and to my surprise I actually spoke with a gentleman he answered all my questions and concerns. I got back onto their site and placed my order for the Tycho. It arrived in only 3 days! I was able to open up the shipping box, removed the packaging material and wow! What a beautiful gift box , I wanted so badly to open this up. I know I can't it's Dan's gift. Craighills communication was superior not only in person but also their emails. I went back on this site and learned about how, when and where their company started and where they are as of today. Any one shopping from here should take the time to read their biography, it will put a smile on your face. I don't think my boss will do a review but his family might and I will mention to them to do so. Thank you so much Craighill for help making some strangers life a wee bite more enjoyable. smiles, linda , Salem Oregon
