I bought this in May 2020. It says the booklet was revised in 2019. Yet Appendix 2,Setting Longitudes for the planets is from 2006 till 2021? Please update the booklet and send me a new appendix 2. You should have some type of container to keep the spare parts in when not in use.
Response from Cochranes: Thank you so much for taking the time to review our products and for you custom. Edit (July 2020): We are happy to have sent you a new appendix and updated the book and passed your comment on the container for the spare parts to our product team. We hope to see you again soon!
