Excellent service: quick delivery that arrived the very same week I ordered, and a very rock solid buffer. Will definitely be doing more business with Rooftop in the future. The pack of ramen and pocket Constitution were lovely bonuses.

Decent. The SOA A5 tube is nicer than the BCM version IMO. They spec the same. Just sayin
