This charger is just the right length to be used in my car. The braided cord allows for the durability to be handled with some force. I am very pleased with the charging speed this cable provides. I will be ordering different lengths from this seller. Top notch!

Ex Output:
positive

Ex Input:
This book is horrible and these reviews must be fake. There is literally 1.5 pages of actual speed reading instruction. The rest is tangential information that will not help you speed read at all. There are tons of grammatical and spelling mistakes. If you don't believe me, waste your money and find out for yourself. This book should not be allowed to be sold on Amazon. Actually, it is inspiring to know that if this Hack of an author can publish this trash and make money, anyone can.

Ex Output:
negative

I purchased this screen saver because of the good reviews. The item arrived, a 2 pack glass screen saver for Apple Watch. I used both screen protectors with the same result, as shown in the picture, the protectors would not adhere properly to the screen leaving significant bubbling. Maybe faulty? One star for product, five stars for customer service. I contacted the seller regarding the issue and they said they would send out another package. Excellent customer service! I will update this review once the new package arrives and I try to apply another screen protector.

Ex Output:
negative
