It's better than nothing but it doesn't replicate anything close to real tennis. Yes, you can practise your technique, timing and spacing but its technique, timing and spacing for a 15mph ball coming at you with a short up/down trajectory...
I think its slightly different for coach because its useful for him to have the option of watching you whilst standing near / alongside / behind you.
See if you can find one on the Bay because otherwise I can see you getting frustrated with this and getting annoyed that you've $X on something that's really quite limited.
