Have a Tennis Tutor Ball Machine for Sale... It is the Jr. Model and is in very good condition. Would rate it as an 8/10! Runs great and is cosmetically good shape. The Jr model is equivalent to the Pro-lite model that is currently being sold. Has the built in oscillator too. I just replaced the battery so it powers up well and holds a good charge. Very light and portable. Only issue is the charger isn't the stock one and has been "MacGyver'd" with a connector to fit. If interested, please email me at firstname.lastname@example.org. Asking $600 obo. Retail is $749 + TAX. Here are the specs of the Pro-lite off the TT website... The Tennis Tutor ProLite™ is a full-featured professional ball machine, yet it stands only 12 inches tall and weighs less than 30 pounds. Patented technology borrowed from the world’s #1 portable ball machine, the Tennis Tutor, makes it possible. FEATURES Five-second Set-up The ball hopper opens in seconds to hold 125 tennis balls. Just load the balls and you’re ready for action. Versatile Speed Ball speed is variable from a gentle toss that’s ideal for kids just beginning tennis, to hard-hitting groundstrokes that will challenge even top amateur players. Variable Ball Feed Ball feed rate is variable from one ball every 1-1/2 seconds (for quick-reaction volleys), to one ball every 10 seconds. Start-up Time Delay A start-up time delay allows the player time to get to the other side of the net before balls begin shooting. Full Range of Trajectories Ball trajectory is manually adjustable from groundstroke to lob. Full-Court Oscillator (Optional) When you’re ready to hit on the run, just flip the oscillator switch and Tennis Tutor ProLite will deliver shots randomly across the court. Battery-powered models The built-in rechargeable battery typically delivers two to three hours of playing time. And it can be recharged between 500 and 1,000 times before replacement.
