The product works as intended, however I missed the plutonium not included piece when ordering so the deal isn't as good as I thought. However, the ability to traverse spacetime for under $400,000 is still a steal just be mindful you will have to still source your own plutonium at least once. Highly suggest traveling forward 100 years to secure a Mr. Fusion for all future travel. Also helps to have maps of future locations so you know you aren't going to wreck into a barn or anything when you come out in the other time.
