iDogmate is committed to the most professional pet ball launcher. With rich experience in R&D of tennis ball machines for people, we fully use tennis ball machines, pets and pet balls (fluffy fibra or saliva status before and after use) to develop the most professional pet ball machines. Complete care for pet family concerns: 1. Easy to teach and easy to learn - big funnel design of 9-1/2" * 9" 2. How to avoid being hit by the ball during learning- Trainer mode will decide to launch when the pet is in the ready and safe position. 3. The pet can use it by itself, and the ball cannot be jammed during use - we design anti-jamming wheels and booster launch design, and at the same time which will have the maximum launch power even for saliva balls. 4. Compatible with 2.5" multiple ball types - booster launch design. 5. Travel support - large capacity 2000mAh battery pack. 6. The pet is overplayed---the rest mode to prevent any exhausted play 7. At the same time, there is an optional iDogmate durable bite-resistant ball (which can be used for 6 months) to help families save the budget for frequent purchases of tennis balls. We also specialize in Pause and Trainer modes for pet and family and dog trainer interactions. Remote control with a display helps the family to know and program the launching mode for different age phases of the pet. iDogmate is committed to realizing the intelligent pet self-ball launcher, and we welcome more comments and suggestions from pet families, let us give our lovely pets a better and better experience. Powerful Shooting Design as well as against any ball being jammed Max teeth (Friction Factor μ) is proportional to the launch force Max contact surface( S) with ball is proportional to the launch force Second-Formed wheel which form the rubber part on Hub as showed red circle. Whish gurantee the rubber part not seperate from hub due to big centrifugal force at high speed, so that the two wheel distance will keep stable to permit the ball launching out. 1. Max Teeth friction factor μ;2. Max Wheel Contact Surface( S) with ball3. Second-formed wheel to stablized the two wheel inbetween. iDogmate maximizes the shooting force to gurantee the max shooting proformace against any ball( wet/saliva) being jammed. Booster Enhanced Shooting Booster design enhances the shooting with impulsive force. These design embrances fluffy fibra ball or saliva ball( bitten by pet dogs) or very light-weight balls.
