Just installed this bad boy on my e-bike and wow, it's LOUD. Like, 'wake up the whole neighborhood' loud. The 110dB alarm definitely makes thieves think twice - tested it accidentally and scared myself!

The sensitivity adjustment is a lifesaver. Started at level 1 (most sensitive) and my bike kept alarming from just wind vibrations. Dialed it down to level 5 and now it only goes off when someone actually touches my ride.

Installation was... interesting. Had to wrestle with the battery compartment - felt like defusing a bomb! Pro tip: use a credit card instead of screwdriver to avoid scratches. The double-sided tape holds surprisingly well though.

Remote works like a charm from decent distance, but changing its battery is an extreme sport - nearly lost the tiny circuit board when it popped open! Maybe keep spare batteries ready before attempting.

Extra features are cool bonuses: doorbell mode made me chuckle (Ding Dong thief alert!), and vehicle finder actually helped locate my bike in a crowded rack. For the price? Absolute steal (pun intended).
