The Haussmann design gives maximum security and control to the operator. The ratchets are spring-loaded and easily operated to control mouth opening. The Economy model is of the same good design but is of poorer quality manufacture, and made from cast stainless steel, as compared to high-tensile stainless steel of the Quality model. Thus the Economy model is more susceptible to shock breakages (being dropped, etc). Talk to your veterinarian about professional-quality Haussmann devices available from Shoof.
