The Stellar Headcollar and Stellar rope have been tested in the laboratory as well as extensively in the field. We have more information on the testing on our website - https://www.equilibriumproducts.com/product/stellar-field-safe-headcollar/ and https://www.equilibriumproducts.com/product/stellar-lead-rope/.
How did you test the headcollar, did you test the rope too?
