Love it. Be careful not to use near brush. This worked so well I ended up tossing a ball into brush on the edge of our yard that I didn't think would be in range and we ended up with mosquito bites and prickers in our skin when we tried to dig it out. I can't wait to go to our local dog park and let our german shepherd really get a good workout with this launcher. Even though this fits regular tennis balls i read that regular tennis balls are not safe for dogs. the microfiber erodes the enamel on their teeth and the balls can collapse and pose a choking hazard. Just a bit of info I picked up recently so I  thought I'd pass it on in case you aren't aware. So stick to the ball that comes with the launcher or something made especially for dogs. I bought a planet dog glow for good 2.5" ball and it fits this launcher perfectly and will not collapse or pose a choking hazard. What a great toy.
