I've used Ridgid 300's since the first days of my apprenticeship beginning in 1976. These machines are truly wonderful, easy to use and extremely robust. Whatever you throw at them, they shrug it off. Dependable and powerful, the 300 is just perfect for all pipework requirements. I've had the misfortune to use "other" makes that look suspiciously alike the 300 and there is no comparison.
The 300 is a true masterpiece, copied by some, rivalled by none.
