Review on Winters Stainless Pressure Internals: Optimized Accuracy Testing, Measurement & Inspection for Pressure & Vacuum by Peter Sullivan

Having an insatiable fondness for sparkling water, I got myself a 5lb CO2 cylinder, regulator and 'Carbo Cap' which you can buy from Revain. To my great dismay, the little tin gauges failed after a few months and never moved again. After a little research I ordered replacement instruments from Winters and they have been working flawlessly ever since.
