Wasn't expecting the remote to be as big as it was but thats not a big deal. Vibration works really good, warning beep is loud. Im a firm believer that if you wanna use a shock collar on your animal you gotta use it on yourself first. Let me tell you i did it on my arm. Started at 25 then 50 then 100. It dont feel good at all. Overall so far im very impressed how nice this is for the cost. Will update later on longevity and distance.
