3 year review.
Works well. Nice and loud. The device itself still charges. Unfortunately the fob battery needed changing so I ordered a battery to replace it. Same spec. The fob is now unpaired with the device and rendered useless. Is there any information to pair the fob and device anywhere?

Good value for money
Been using this for a while very happy with the results, easy to use very loud and very sensitive if anybody wants to touch your bike. This is a very good little product

1 faulty out of 3 but a good alarm
Got the battery one of these nearly 2 years ago and it's always been great and very sensitive and alarm'y when it should be. Because of this, I needed a new one and decided to get the rechargeable one this time. Charged it up, tested it in hand before fitting it (possibly didn't test its motion enough though) and fitted it... But would only go off if I physically shook the bike (unrealistically hard). Deemed it faulty so spoke to Amazon. They offered a refund for me to reorder, and the new one came, tested it (more thoroughly) fitted it and it's perfect. I put a light weight plastic bowl on the seat as I walked past it without thinking and it chirped at me like a proximity alert, so definitely works now. Test it works before fitting it as that was a pain to disassemble, reassemble, then disassemble and reassemble again. Glad I got it though!

Versatile, good battery life, reliable.
I have several of these, and all work perfectly. Obviously designed primarily for cycle or scooter protection, but I use them for all sorts of other purposes such as I have one attached to my garage doors, another hidden in my car, not loud from outside but trust me you don't want to be sitting inside the car if it goes off and you don't know where it is.. So I really recommend these for all sorts of purposes, and being rechargeable rather than having the need to replace normal batteries is a real bonus to me. Battery life between charges is also very good.

Snapped off
The mount snapped when I went over a bump and the whole mechanism bounced away. It still works but I’ve attached it to my bike shed rather than having it on my bike as it’s very easily removed. Can’t really use it as a horn as the key fob is too small and fragile to mount to the handlebars, it’s a good alarm, very loud and sensitive but you’d need to be ready if someone was stealing your bike. It might deter an opportunist or stealthy thief but some would just smash it and go about their business. Good for the price but impractical for what I need.

Acerté de pleno, un gran precio para una gran alarma, muy configurable, en sensibilidad que es lo importante y en sonido, que es menos importante según mi opinión, pero bueno, eliges la más aguda que mejor se oiga en donde aparcas y listo. La batería no la he gastado aún en un par de meses, con encendido y apagado diario, se carga por USB así que te ahorras pilas y el tener parada la seguridad por no tener pilas para ello. El mando funciona lejos y bien, con función de encontrar el vehículo y doble aviso de encendido. La alarma en la mayor sensibilidad es muy muy eficaz sin falsas alarmas por vibraciones de motores o similar, pero si tocan, suena, a la primera, con avisos y luego alarma. Gran producto.

Klasse funktioniert sehr gut. Artikel kam wie gewohnt von Amazon sehr schnell an. Ausgepackt und die Hupe über Nacht an USB geladen. Die Fernbedienung hat schon volle Batterien. Kurz getestet und geht gut. Nun habe ich die Hupe am Fahrrad montiert und getestet auch alles gut und funktioniert. Man musste nichts einstellen weil alles schon voreingestellt ist. Verwendbar auch als Fahrradklingel. Werkzeug und eine deutsche Beschreibung ist auch alles dabei. Das war ein guter Kauf.
