OLenyer makes a compact ball launcher that solves a real problem: your dog wants to chase, and you want to sit down. The 2-inch mini tennis balls fly between 10 and 30 feet, which is enough range for a backyard or a long hallway. Three fixed settings let you dial in the distance, or you can flip to random mode for throws that keep your dog guessing. The whole unit runs on one included 12V battery, so setup is plug-and-play.

The build is simple and functional. At 11 inches wide and 8.5 inches tall, it takes up about as much space as a small cooler. The throwing mechanism is loud enough that most dogs perk up at the sound, which helps with training recall and anticipation. The random mode is the standout feature here. Dogs figure out fixed patterns quickly. Random throws keep them engaged longer and burn more energy in less time.

One honest limitation: the launcher only works with the specific 2-inch mini tennis balls it ships with. Standard tennis balls won’t fit. Replacement packs are easy to find, but it is a dedicated ecosystem. For the price, it is a solid tool for high-energy dogs that need structured play without requiring you to stand and throw for an hour.
