Collar to prong safety strap, backup clip, collar safety strap

Safety strap, looks ok, nice...would I trust it as safety clip? Not really to be fair. Will have to buy it again from a different seller. If the dog get spooked or reactive and lunge towards another dog, don't think the clip will strong enough. Delivery time absolutely horrendous! Took something like 2 weeks to receive it maybe more! Most sellers on Etsy, deliver it as first class.
