Customer Reviews for VEVOR Portable Tennis Ball Machine—APP Control Count—5 Out Modes—29 Out Lines—Custom 1-20 Point—Adjust 20-140 km per h—40 Pounds—Lasting 6-8 Hours—150-Ball Capacity
Comparable with competitive models costing $800+ more.
A little heavy and bulky but all others are the same.
The only negative is that it does not have an option to change the elevation/height of the ball.
Very solid machine at a great price.
