Bests & Worsts Reviews from Amazon

I've been using this for a few weeks now and so far it's been working great. I prefer to have my dog walk off leash in the trails behind our house but my dog has been known to run off if he catches a scent or spots another dog from far away. So, this e-collar has been a great way to keep him at bay while still giving him the freedom to roam around away from me and sniff things to his delight. I love how the collar and remote are both rechargeable (it would've been nice if they provided two AC adapters - I charge the remote one night and the next night I'll charge the collar). The waterproof design will come in handy when it rains The remote does shut off after a few minutes without use. While walking, I'll check the remote every few minutes to make sure it's on and if not, press the mode button to wake it up. I wish the remote had one button for vibrate and another button for shock but instead, you have to cycle through the modes using the mode button. It's not hard to do since there are only four modes (shock, vibrate, chime and I'm not sure what the fourth one does...). So you just have to know what mode your remote is in and if you need to change it, you only have to press the mode button no more than 3 times (e.g. mine is usually on vibrate but sometimes I need to quickly change it to shock) No real gripes about this item which is why I gave it 5 stars especially for the price. I wasn't about to spend $100 for an e-collar and this one does everything I need it to do
