Lens are super reflective making everything blurry. They do not reduce eye strain, on the contrary, they make it worse. I wouldn't waste your money on these.

Ex Output:
negative


Ex Input:
I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.

Ex Output:
positive


Ex Input:
I ordered 1 case/ 6 individual (1 liter milk cartons) for $34. But only received 1 damaged individual 1 liter carton. I want to know where my other 5 cartons are????? I can't find anywhere to contact to fix this! I will never be buying from this seller again. :(

Ex Output:

negative
