I bought this Millenium MPS-850 pad for my Roland TD-1DMK drum kit.
The trigger worked well when the beater was set to the very bottom of the net. In order to get feedback from the center of the drum, like other buyer reviewers, I pasted a felt circle on the foam of the trigger, which improved the responsiveness. The mesh is thin, single (in comparison with Roland - there is double). For the experiment, I set a regular Roland pad (PDX-8) as the kick drum - and it was much more sensitive than this MPS-850 pad (very weak hits are not always caught). In the future, I will try to move the trigger itself to the center of the drum, I wonder if this will improve the sensitivity by 100%. In principle, the product pleased me, this pad is more interesting than the small rubber pad from Roland TD DMK-1.
