Ex Input:
After the third use it did not charge up any more. Ok if you want a disposable charger to throw away after only a couple of uses. It worked ok for the three times that I was able to use it. However it did not charge my phone to 100%, only to 80% before it lost all of its charging power. I did not have a problem plugging it in to my Pixel 3 with a case on it. But that doesn't matter now as the charger does not work. Seriously, do not purchase this product. Other one star reviews can attest to the same fault.

Ex Output:
negative


Ex Input:
This item was much shorter than I expected it to be. I have an alaskan malamute and this did not do the trick in trying to help with his pulling. If you have a small dog, this will work for you.

Ex Output:
negative


Ex Input:
I was very impressed with the quality of this light. It has a nice sturdy feel to it and is extremely bright. The 3 light modes give you various options for the situation. Once the light detects breaking motion it gets even brighter, works almost as a car tail light does. It comes with the bike seat mount and also a rubber strap mount to give you more mounting options.

Ex Output:

positive
