The pad looks and feels like a high-quality product. It is small and light enough to be easily portable, but it also has a nice weight so that it feels solid and doesn't move around too much. I like both playing surfaces. The green side is quite similar to a RealFeel pad in terms of rebound and volume. The grey side is a little softer and quieter and has less rebound so that you need to use your fingers and wrist a bit more when playing on it.
All in all, I'm happy with this pad. It is a bit on the expensive side, but you also get good value for money in my opinion. My only minor concern is how durable the grey fabric is in the long run, but after using it for a week or so, I don't see any signs of wear on it. Apparently the same surface is also used in the Prologix ALLN1 pad which has been around for some time and I haven't seen negative comments about it so far.
