In this task, you're given a review from Amazon. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral, 4: good, 5: extremely good.

Pro: Picture quality is very nice Pro: Sound is good enough for the purpose Pro: Price is good Con: When the unit is rotated 180 degrees and folded shut (as it would be in a car mount), the convex monitor backing can push the function buttons behind it when even the slightest amount of pressure is applied (like a toddler playing with the TV with their feet). Often, playback is stopped as a result of these interactions. Con: The remote works, but reception at the unit is a little sketchy from just a couple feet away. Often have to push buttons more than once to get the unit to respond. Con: The headrest mounting case has a strap that covers the On/Off switch in the unit. Since you cannot toggle the unit's power from the remote, it can make things awkward. Con: The cigarette lighter adapter has a short cord (two feet long, tops). I was lucky and already had an extended adapter that fit this unit; otherwise, I would have needed to buy a different adapter to use this unit in the vehicle. It would have been too far away from any power source. I don't dislike the unit - and doubt it will get returned - but had I known these things going in, I would have purchased a different unit.

Had this welded onto my old Legacy GT and it sounded great! Only downside is you can tell the quality of metal is decent but not great.. hit a curb coming out of the driveway a couple times and it bent the very top flat almost and pretty easily but I'll give it the benefit of the doubt considering my car was pretty low, so as long as you're not hitting dips and curbs it'll hold up well. With that being said the first week I had it I had to carry around a bottle of water in my car to hose down the inside every time I parked and got out as the fiber glass inside is either too dry or just awful quality and would literally light on fire and dump smoke out of my exhaust! After it had all burned out my car was even louder and sounded pretty sweet but I did have to worry before then that my car would light on fire if I didn't put it out when I parked.

I was not able to drive onto them as they frustratingly squirted out from under all four tires at every attempt in my garage. So a jack will be required to lift each corner to position them under the tires. And my current floor jack is not low enough to fit, so to even use them I need to buy a new low-profile jack. It's not worth the extra expense and hassle, so they hang in my garage unused.
