I have owned three different set of Dogtra training collars. This was my newest purchase and I am 100% satisfied with these collars. The battery life is impressive and the remote setup is perfect for our use. The intensity range is great for us since one dog has extremely low sensitivity and the other has extremely high sensitivity. The ergonomic design is nice and I prefer it to the old block types that would get caught on everything.
