Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Can't use it outdoors at all due to sun interfering with infrared control. Seemed hard to control indoors due to lack of stability -- took a lot of focus to just keep it steady in the air and then make it fly directionally without hitting walls, ceiling, furniture. Ran out of battery charge in about 10-15 mins, and charging isn't very fast. Having said all that, my boys (ages 6 and 4) were still having fun with it. Until it wouldn't work any more. At first the remote worked only intermittently. Then one of the rotors stopped rotating entirely. Had to send it back for refund.
