Not only is it visually stunning, with an appearance that will shock you when you see it for the first time, but its the only game app on my phone that I play every day... several games. Maybe a whole tournament (at least 7 games). This is worth a lot more than they charge.
The only complaint I have is that the tuning of the controls changed when the app was updated to support the iPad. The first version that came out after that was unplayable on an iPhone, at least by anyone who had been playing it previously. However that was quickly addressed with another update, supporting user adjustments to the control sensitivities for forward/backward and rotation. It took a bit of experimenting to find something similar to the original excellent default tuning. So if you try it, out of the box you might love it except for the controls, if so, dont loose faith. Ive set mine to Slide: 80 and Spin: 17 and the spin might be a bit too sensitive still, but those arent bad places to start your experiments.
Oh one other suggestion, try setting the puck to Grippy. I find its more realistic in terms of real hockey, perhaps not as realistic as the bouncy pucks would be for table hockey, but I find "Grippy" to be more than enough bounce and slide.
Overall, should you get this? Absolutely. Its amazingly great. Im about to download the latest update which has fixes for the other two areas that could probably use a tweak: puck handling by the computer, and (as is always the case for hockey games) smarter defensive AI. Sounds great!
