I agree about the ecollar. We held out for years thinking it would just take practice to get perfect recall, but no, the ecollar is a game changer. Kaiser will just see my hb reaching for the remote and he starts being more attentive and will often come back with just a verbal call. That extra insurance is priceless. Like a seatbelt in a car as @LifeofRubie once explained, you never want to have to use it, but it'll save your life if something unexpected happens - that logic sold me on getting the ecollar.
