Question: how do you access the 3 new drills (since theres no dedicated button for Lefty, Moonballer and Slicer?..)
Document: While most people would be fine with the Lobster Elite 3, I've felt the fully random oscillation which includes spin variation (Elite 3 does not) and the extra drills were worth the additional costs and allows me to advance my game. I also believe this Lobster and other Lobster models are far superior in its ease of portability which makes these machines better than other comparable (function wise) out there.
I used the random horizontal and the drills where I can control how fast the balls are shot, to build up to this program myself.The three preprogrammed drills (Grinder, Baseline and All Court) are usefully drills to practice movement and strategy. The placement is accurate to the descriptions/pictorials of the drills. On the baseline drill, you will even get a good shot landing inside the service line.
I bought a used unit for a couple hundred dollars less and it has worked perfectly. The charge seems to last a good while. I use it about an hour per day so only charge it about once a week. The remote is a must and very convenient when  you want to change drills on the fly. On to the drills themselves. I will use a narrow  2 line drill to warm up both forehand/backhand then switch to one of the other drills. The grinder on random is a beast.
Package delivered promptly by Amazon, as always. Turns out the wrong charger was put in the box by Lobster when they shipped it to Amazon. I called Lobster and they politely told me they'd send the correct charger - should arrive in 2-3 business days. A week later I called again and they had no record of my phone call about the charger. They took my details and said they'd ship another one.
In addition to placement, you can select from short, midcourt, or deep court placement. I use the 3-line feature to practice alternating backhands and forehands, and use the wider feed placements to practice "on the run" shots. A coach would benefit from the 3-line mode because you can feed alternating balls to two to three different players. All three settings will hit accurately in the singles court.The Random Sweep Options (horizontal and vertical) are also very good too.
The red casing consists of a hard plastic. Baring any dropping mishaps it will surely last a lifetime of ball pelting and transporting. The Hopper stays on well and feeds almost all the balls (minus the occasional one or two stuck in the back corners). The new foldable handle is probably the weakest part of the machine in that it doesn't feel as sturdy as it could.
I ordered this machine about 2 months ago and have used it at least once a week since receipt. This is a great product. It will definitely improve your game and fitness level. It has features for all levels of game play. If you are on the court by yourself often, I would definitely recommend getting the remote. My family and I will have years of fun using this machine. It seems very durable and made with quality. The only negative feedback I have is with the power source.
Unlike a human, the Grand IV does not get tired, will not call your ball out and returns it every single time. You will want to get 150 or so pressureless balls to use but if you're really into tennis and improving your game, it is a worthy investment.
Thsi featre to me is unique and must as in real match play you don't get balls at the same speed. Moreover, Grand IV offers 6 preset  match plays which I found it usefully.Lopster is also lighter an easy to carry with you in a small car. I have Chevy Volt and its fits pretty well. I have been using this machine for the last 2 weeks and love it.
The Lobster Elite IV Grandslam is a fantastic training machine, but more importantly an excellent simulated player. The Lobster feeds out a realistic ball with great topspin/underspin and good "heaviness". When using manual mode you can "groove" your groundstrokes ,  overheads, and volleys and advance your training as you progress by changing any one of the spin, feed interval, and elevation adjustments.
Answer: yes
