Review on Tennis Ball Hopper Tube for 16 Balls - Tennis Ball Pickup Collector and Retriever Tube Carrier - 40in by Tay Tran

Works as it should - holds 16 tennis balls, comfortable adjustable strap. I deducted 1 star because the plastic is not very heat resistant. Without thinking, I left him in the car one night, coming home from court, leaning against the front seat. The next day was sunny and warm. When I got in the car later that day, the heat was causing the pipe to buckle. So now the bullets get stuck in there. Now I know I shouldn't have left it out in the sun, but there should be a warning as it's not something you might think. If you leave it in the car, leave it on the floorboard or in the trunk and out of direct sunlight.
