I received my new tennis tutor player plus model on 8/8/06. I wasn't going to buy the player model until I discovered that Sports Tutor had a demo model available at a reduced price. Below are my initial impressions of the machine after using it in two 90 minute sessions. * The machine is lighter than I thought it would be. It has a handle that allows you to carry it around and that makes it easy to move it across rough terrain. I'm big (6'3") so its relatively easy for me to pick up for short distance. No one would want to carry it very long however. For the more petite player it also comes with a fold out handle that enables one to pull it along on two roller wheels. Perhaps because I'm tall, I wish the handle was a little longer. * The unit seems VERY sturdy and well put together. Nothing shoddy about its construction. * The packing box contains the completely put together unit, a 10 page user manual and the charger. I bought the smart charger so I would not have to worry about overcharging the unit (the standard unit has to be manually unplugged). * The top of the unit has four plastic flaps that fold up and out and are used to hold the balls (up to about 150) in place. They are made of white plastic. I wish the front one was made of clear plastic so I could see how many balls are left. I've already hit these flaps several times and they seem sturdy enough. I understand that they are replaced for free if something goes wrong. * I had a supply of used tennis balls ready to break the machine in. They recommend that new balls not be used. Even with my used balls a lot of fluff was churned up during my initial two sessions. I have an air compressor and simply cleaned that stuff out after the second session. It wasn't a problem its simply me being a new picky owner. They say you can run 100 hours without doing this kind of cleaning. * The battery charger works fine. It took about 10 hours to initially charge the machine but that might be because it was a demo. The instruction manual says it can take up to 18 hours. After my first 90 minute session it took about 8 hours to recharge the machine for day two. It was a good decision to get the smart charger because I didn't want to constantly have to worry about overcharging and have to go to garage to check the status lights. A fast charger is also available but I didn't think that was necessary for me. Perhaps if you give lessons or have multiple people using the machine then that would be nice. For me, an overnight charging period was fine. * If you select slower shots you'll need to place the machine closer to the service line. If you're hitting medium or higher paced shots then baseline placement works best. * The control panel on the player plus model has all digital readouts. It has an off and on switch and the machine seems to remember the settings that were in place the last time it was turned off. * The player plus has all the features of the plus model including ball speed, elevation, spin (top/under), interval, oscillation (random, 2 line narrow, 2 line wide). Additionally it has the "fancy" player mode capability (more on that in a moment). * One of the first things I did was crank the machine up to see what it could do. After adjusting the elevation and top spin I was able to get the machine to send across balls that anyone except Federer or Nadal would be challenged by. It will be a LONG time before I outgrow this machine. Actually since I'm over 50 I doubt I will outgrow it, but one has to dream. Whether or not the ball actually reaches the promised 85MPH I can't tell you. But I promise you that it has plenty of horsepower for any player I've seen on the league or tournament courts. * I was able to work with the elevation and spin to create almost perfect lobs for practice. It took some twiking but once the setting were correct only slight variation was experienced and I contribute that to the balls themselves. I wish they offered a feature that allowed you to save, say 5-10 settings so that you did not have to manually adjust the machine each time. For example, it would be nice to be able to save setting for shallow lobs, deep lobs, deep hard topspin, etc. * The oscillation feature works fine. I tried the 2-line versions (narrow, wide) just to make sure they worked but did not spend a bunch of time with them. The random oscillation worked fine. The way the machine does it is that it actually sits on the court through a steel plate attached to the main black portion of the machine through a motor(s). The machine turned left and right riding on this plate. It shoots balls out at random times. * The internal setting goes from 10 seconds to 1/2 second. I had a problem with the longest two settings not turning the wheel that feeds the balls into the machine when a lot of balls are loaded. Obviously it works on some friction setting that is increased as the time internal is reduced. The slower setting simply did not turn the wheel enough to overcome the weight of the balls in the "hopper". This was not a big deal to me because I'd probably never use the 8 second+ settings while using the machine. 10 seconds seem like an eternity when using a ball machine. NOTE: THe slower speeds worked if fewer balls were in the machine. * It took me a while to completely understand how to sit the machine up. It would of helped if I had read what little manual came with the machine. The "secret" if the center button that insures the machine is lined up on the steel plate that sits on the court. Just because the slot the balls come out of is centered that does not mean the machine itself is centered. Its all based upon the positioning of the steel plate on the court. This button makes sure they are in synch. Then you can align the machine to the desired court position. * The player mode feature was initially disappointing to me. Perhaps my expectations were to high? In my mind I was expecting a machine that would send balls at me like I was playing a player of the selected ability level (beginner, intermediate, advanced). In other words simulate match conditions. The thing I noticed immediately was that balls did not come at the interval one experiences during a match. While the machine does vary the depth and placement of shots it also seems to send a lot of balls to the same place. I've only used the default settings so I think i need to play with these more to get it closer to real match conditions. * Overall I'm very happy with the machine and am looking forward to many years of great practice and soon having perfectly grooved strokes.
