I immediately started playing random beats on the Drumeo P4 practice pad when I received it. It was very bouncy, my wrists felt free, and I wanted to play on it for hours. Now I find it very useful to warm up my wrists before practicing on my Roland V-Drums kit. The rubber on my V-Drums isn't anywhere near as bouncy as the practice pad, and this has made me realize I need to upgrade to mesh heads as soon as possible.
There are four different rubber surfaces on the pad. The blue surface feels like a snare drum, the black surface feels like a high tom, the gray surface feels like a floor tom, the red surface is the hardest and feels like a high-hat or ride-cymbal. This is fantastic because it resembles an acoustic drum kit. I can easily take it with me anywhere as it's small enough and light enough to fit in my backpack and gives me a diverse practice experience anywhere.
My favorite surface is the gray surface. It's very quiet, bouncy, and soft. If you hit it very hard, you can hear the wood sound underneath so, it makes me remember to practice hitting softer with correct technique.
Overall, I'm using it every day. I'm having fun with it. I love it. I recommend it as a warm-up tool and portable kit to practice when you're out and about, in the car, at the airport, waiting somewhere, etc...
