awesome product ,,, but,,, not so different from SoundOff mesh head if you put some duck tape on it,,,,so if you already have SoundOff mesh,,,it is not big upgrade.....triggers working awesome....If you use it with resonant heads it is full acustic drum ...but with low volume....you only need to tune to that sweet spot ,,,it is only one spot that sounds awesome,,,not like regular drum with normal heads with many options....for example reso head need to be more down with tune ,,,not so tight like it is on normal drum..... so first tune reso to get some nice low sounding with lots of sustain.... and then tune batter head and listen sound as you tune up head from finger tight...
