Break light

I was very impressed with your product. I didn't like how the alarm doesn't go off when it is first touched by a potential theft.
Great so far

Just installed this on my bike and tested it out. It is very sensitive and gives a warning beep before the alarm. The are several brackets included for install in different areas of your bike and the instructions could be a little clearer. Over all it is a great product for little money.
braking light works great

this alarm/taillight is a great innovation. With 2 mounting options - 1 is a mount attaching it to underside of the seat the 2nd is to mount it to the seat post. I would suggest they create a 3rd option to mount this to the back side of a rack. I was able to make this work by modifying the one mount, and it does work but it would be better if there was a solid mount for the back of the rack.
La sirena suena super fuerte

Las compré para mi bici, scooter y moto, son realmente útiles.
Nice and loud. Very (too?) Sensitive

Just got my new Lectric XP ebike and want to feel safe parking at grocery store for short periods of time. Bought a good lock but wanted the alarm just in case. I live in a pretty low crime area and doubt anyone would actually continue to work on stealing it in a busy parking lot during the daytime. Haven't had this long enough to rate the battery life. My main concern is that it is extremely sensitive to vibration and gives only one warning. If I chain my bike to a bike rack I fear the next person who tries to chain next to me will set off the alarm. Super loud... super annoying for them and anyone around until I come out of the store and turn it off.
