Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.

Positive

I have always had trouble finding the perfect toner for my skin type. I have oily skin but it is also extremely sensitve to burning and tingly toners that contain alcohol in the ingredients. I have tried a lot of toners, and this is truly one of the best ones I have ever used IMO. It is very gentle and does not produce a burning or tingly sensation after application. It has a great, light, clean scent and does an effective job of wiping away any remaining oils/dirt on your face. I like to use it after cleansing and prior to any day/night moisturizers.

Ex Output:
Positive


Ex Input:
LJS's other books are great, but this one was so boring! There was absolutely nothing dangerous about Gillian and David being in love, and that's the whole point of this series! Also, it's kind of unlikely that someone could just cut her hair and wear makeup and then suddenly be popular. I didn't like Gillian at all. She's superficial, not to mention being Little Miss Weakling. David was an idiot because he fell for her as soon as he saw her with short hair and makeup. Let's get realistic! He cheated on the SATs and Gillian still wants to support him. Plus, he's BORING! LJS's other books are all 5 stars in my opinion, but I hated this one.
