In this task, you are given a set of reviews from Amazon and Yelp. Your task is to generate a summary of a given set of reviews about the information present in reviews. This generated summary should reflect users' common opinions expressed in the reviews, the common sentiment of the opinions and their details, and should be coherent with the given set of reviews in terms of sentence and information structure. Avoid creating summaries that (i) contains additional information which is not present in reviews, (ii) look exactly like the review, and (iii) uses 5 or more same consecutive words or phrases given in the reviews.

Let me give you an example: Review_1: The only thing I would like to see is an aux cord when I don't want to charge my phone, but It's not a huge deal. The sound is great, and worth the money. The remote works with your phone, and that's precisely what I wanted, Review_2: you need to buy an adaptor for Ipod Nano's so it was disappointing when my son opened it up on Christmas and could not use it for his Ipod Nano. It does not state that anywhere on the box or when I ordered it., Review_3: Love, love, love the ability to save multiple preset radio stations, and the sound is clear, crisp... amazing! It almost makes waking up a pleasure. Another feature I never thought I wanted, but really appreciate, is the ability to set the brightness of the clock readout. Brilliant!, Review_4: The sound of the radio is of real quality. I also like having the two separate alarms and the alarm is not obnoxious yet still wakes us up. My wife charges her iphone on it regularly and works out well. We like the Sony so much I got one for my son and his wife for a Christmas present, Review_5: I was looking quite awhile to locate a decent sounding radio / iPod player which would also charge my iPod. This is perfect for our family. It's a lot smaller than I thought, which is good. And when we update to an iPhone 5, there is a $5 adapter to get so we can still use this radio. Perfect!, Review_6: As always, Sony has a 'winner' in this combined am / fm radio and docking station. Great sound, looks good and wife is very pleased as she put it in her craft work area. Finding the combo of am / fm wasn't easy either.Lots of fm only units. This is a great product., Review_7: My husband really like this speaker... LOVE IT! Its so easy to operate by setting the alarm.. I like the way when you put your iphone 4s to the dock its charge at the same time while you are you using it...! Great product, Review_8: While I like the Dream Machine I don't know why there's so much static. It's nearly impossible to get a couple of my favorite radio stations without constant static in the background. My other radio doesn't do that. I've even tried different locations for it. That's a big disappointment and shortcoming of the product.
The answer to this example can be: This FM/AM radio, iPhone docking station and alarm clock is a perfect combination! The sound is amazing, the alarm clock is not annoying, and the design looks great! It would be nice to have a place to use an aux cord and certain apple products require a $5 adapter to use the docking station but other than that, this product is fantastic!

OK. solve this:
Review_1: I looked at a few sizing charts and they said that 'one size fits all' will fit a head with a circumference of 21 1 / 2 '- 22 1 / 4'. My head is 21 3 / 4 'and this hat sat on the top of my ears! I have returned it., Review_2: Loved the stitching design, got a lot of compliements on it. The best part is you can roll it up and pack in your suitcase for travel and it unfolds beautifully. Provides the right amount of coverage and stayed on my head in windy conditions., Review_3: I needed something for my cruise to Hawaii. I ordered this atthe last moment, but Amazon came through and I receivedit the day before I left. I love the look, the feel, the factthat I can fold it and stick it in my suitcase and, best of all, I received compliments on it., Review_4: I spent 2 months at the beach this summer and this hat was great. It kept my head cool even in nearly 100 degree weather and also kept my face protected. I have a fairly large head and had no problem with the one size fits all., Review_5: I wear a hat anytime I am outside for any length of time. This hat is cute and provides great sun protection. I have a hat for hiking and a hat for the beach, but this is for more dressy occasions like an outdoor birthday party or a trip to Butterfly World with my granddaughter., Review_6: Good quality hat, I love that I can be protected from the sun, and look good too! I'd also like to commend customer service, which was responsive and helpful when I accidentally shipped my order to the wrong address. I have already ordered another hat for my daughter., Review_7: I bought two of these hats to keep on our son's boat. They are pretty stylish but most importantly does protect my hair and face from the sun. Love the UPF protection. The only nominally downside is it is difficult to stay on when the boat is going fast. I think for wear at the beach or just outside it is a great purchase., Review_8: It looks good; it's comfortable; it keeps the sun off my face & neck. I wear it while gardening or for walks. I got it in the Moss Green and the color is as shown online. I'm glad I bought it.
Answer:
The hat is comfortable, stylish and easy to pack into a suitcase for travel. It protects well from the sun, keeps the head cool, and is suitable for both boat trips and more dressy occasions. Sizing is 'one size fits all' which seems to be good on even large heads. The customer service was great, ensuring the product arrived on time before travelling.
