My new SportDOG dummies have stood up to the grueling weather we had in December - just like the ones I bought 20 years ago (and still use) and very much unlike a different product which shattered and cracked in the cold (that I had bought elsewhere before I found Outside Canada Sales).
The orange colour being much brighter than on any competing product, they are highly visible, especially in low-light conditions. The didn't come with a rope, but I don't mind because the usual rope length on those dummies is too short for me anyway. And for those complaining that their dog chewed off the valve or other parts - it's a training dummy, not a chew toy!
