This is essentially the same trigger as the one ddrum manufacturers except its yellow. Not exactly worth the amount that you pay. Just buy the ddrum trigger.

I bought a pair of these after my ddrum triggers were stolen after a gig, and how I wish I hadn't. Don't let the similar price tag fool you, these things are way less durable than the ddrum triggers. After three days of use, the cable connection housing on one came loose, so the cable would wiggle back and forth with the vibration of the bass drum, causing ridiculous amounts of double triggering. After a week, the other trigger was having the same problem. Definitely not worth the money.

I bought a set of these a few years ago, and I can't believe this company is still in business. Beware, this trigger will damage your bass drum. What is not pictured is the little cap on the end of the mounting thumbscrew that comes off easily and will scratch your rim. The foam rubber contact wears out within months. The 1/4" jack comes unplugged easily. Don't waste your cash on these - get the ddrum triggers.
