This is my 4th tennis ball machine I have owned. I currently have a Lobster Grand IV (over 1+ year) and SpinShot Player (six months). Either machine is such an improvement over my 2nd ball machine (from Lobster), which I had last 15+ years until its pneumatic compressor gave out. (Some Kudo's for Lobster, as good as their advertisement)I love my SpinShot and Lobster Grand IV, using them almost 4 times a week, each time shooting over 200+ balls, primarily for my daily exercise as my doctor ordered. My primary job is located in Far East, but my home being in the SF bay area. When I am in Far East, I use my Spin-Shot, while at home depending on my Lobster. Both machines delivered on their promises, performance and reliability. I love both of them.Many of my friends have asked me to compare the two. It is very difficult in my opinion to compare the two machines, both being superb machines, with a Lobster Grand IV being about $300+ more expensive than a SpinShot Player. The SpinShot player gives programmability, more control on each shot, and remote control through Iphone or Android phone. (I have only an Android phone, while the rest of my family on ardent Iphone users.)One thing I have noticed is that the highest ball speed in the SpinShot looks a little bit slower than that of the Lobster. For my level (3.5 to 4.0, depending on what day it is), it does not make much difference at all, but if someone is a 5.0 or better player, it could. If one sets a SpinShot at a feed rate of 2 seconds (its fastest feed rate) and use it for 200+ balls, then, the battery seems to become low (or discharged substantially). There is such a drastic decrease in the ball speed. In my opinion, this has more to do with the battery provided (12 Ah, 12 V) in a SpinShot being on a weaker side. (Lober Grand IV, 18Ah, 12 V). I have ordered an external battery extension option from a SpinShot, which I hope will solve this problem.As I told my tennis partners, I love both of these machines and in terms of reliability and showing up on time on the court, they are far more reliable than my tennis partners....
