Furlihong 3807BH Tennis Ball Machine with Triangular Base, Adjustable Speeds, Oscillating Left&Right, Up&Down Swing Launch Port, for All Levels Training

Updated review after support from the seller - The seller was very helpful to provide support. It looks like previous unit i received was badly damaged during shipping by Amazon. Exchanged unit is working fine with very good packaging. Throwing range is little less than what is specified in the specification. Throwing angle reduces as you go over 15/20 minutes in the battery. I guess this might be battery issue. I have not tried this long plugged in. Overall, this is very unit at this price point with three axis automatic rotation - very helpful to practice alone.

I was pleasantly surprised at how well this machine provides a good workout with a variety of ball height and speed. Assembly was easy and I bought rechargeable D cell batteries and a charger. I used the machine for the first time today and did 3 sessions of 30 balls and the batteries were going strong. The only complaint is they could provided a little better instruction on the settings on the ball speed, oscillator and ball height. I strongly recommend this machine as a teaching aid as well as a workout for you if you have no partner to play with.

Machine worked great at first, however after 1 use the motor stopped spitting the balls out of the machine. Reached out to the company and they have a 1 yr warranty and provided a full replacement

This machine is well-build. I got this in Jan and have used it for 2-3 times as it's cold outside. It launched tennis balls at varying distances and angles, feeding through an entire set seamlessly. I am not big fan of running on batteries therefore I bought a portable Power Station 500watts. Customer service is excellent as they are prompt in responding. A couple of my ball-feed tracks were compressed but the customer service replaced them free of cost. Although you can disassemble them after practice i prefer to keep them assemble so don't waste much time next time (just remove it from the main unit). Machine throws balls in different directions, and good for both practice shorts and work out. It is portable, and everything fits into a the duffle bag that come with it. I will likely try it more in next couple of months and may give the update how it worked during summer.

Awful product. First one rotors never worked and had to have the product replaced. Second one went through one round of balls and the rotor stopped working again. Not worth it in the slightest.
