Ex Input:
Not impressed. Battery failed to charge after two weeks. Got an authorization to send it to Asus, and when they sent it back, "repaired", it would not turn on. Shipped it back to Amazon for a full refund. Since then I've seen this puppy for $299 on Groupon. Don't waste your time or money. The upside is the ASUS employee I spoke to was very courteous, and sounded Amaerican. Unfortunately they can neither make, nor repair a tablet computer.

Ex Output:
Negative Review

Ex Input:
I have tried several docking stations and this one works very reliably and is well designed. If I could afford to, I would replace all the other brands with Startech. It looked like I saved money with the others, but I really didn't.

Ex Output:
Positive Review

I have been using a stylus for two years. I have tried a bunch of them mostly the cheaper versions. I received a new Kindle HD Fire for Christmas and found it was necessary to use a good stylus. I invested in the Amazon Basics because of previous reviews and extensive research on the best one. There reviews were correct. The money was well spent and the product is terrific.

Ex Output:
Positive Review
