I love the Chuckit products, using a tennis ball. The ball that is included pops or unravels in minutes, and the quality of the ball has gotten worse. On the other hand, the handle lasts for years (unless your Lab gets hold of it). I keep one near the front door, and one in each of my vehicles. I contacted Chuckit and they said they would replace the balls. I filled out the paperwork, sent pictures, and they blew me off. (No customer service.)
