Let me start by saying this alarm is a GAME-CHANGER for golf cart owners. The magnet mount installation took me literally 30 seconds - just stick it to any metal frame and you're done. No tools, no wiring headaches.
The vibration sensitivity is impressive. When testing it, even gently rocking my cart triggered that EAR-PIERCING siren (seriously, cover your ears). While some reviewers wished it was louder, in my suburban neighborhood, it's definitely loud enough to make thieves panic and neighbors notice.
I especially love the remote control feature. Being able to arm/disarm from 66 feet away means I can secure my cart while walking toward the clubhouse. The rechargeable battery lasts weeks between charges in my experience.
One pro tip: Like one reviewer mentioned, aluminum frames can be tricky for mounting. I solved this by using the included magnet on a steel bolt head under the seat. Their customer service (yes, REAL humans answer!) actually suggested this when I called.
The only minor con is the alarm doesn't have adjustable sensitivity - sometimes strong winds trigger false alarms. But for under $50? This provides way more security than those $150+ wired systems. Pair it with that $7 battery switch hack mentioned in reviews for ultimate peace of mind!
