They are great Boosters...but there again since we are the US distributor, we may be a little biased. These ROB Boosters sold by UPD are actually Maximator Gas Boosters made in Germany. Our price here is US1700.00 and always available. Go ahead any but it. It beats the Jetsam, Haskel Mini Booster etc any time. We can send you referals if you want them.
