Review: Very loud - Very loud, definitely makes people aware you are there
Review: Doesn't ring like a bicycle bell - Strange product, very nicely designed, easy to instal, and looks good. But it is programmed to make 3 different noises, none of which sound remotely like any kind of bicycle bell. Sorry but this is moronic, how could someone design something which cannot actually do the only single thing it is meant to do. Guys, a bicycle bell needs to sound like a bicycle bell, not a car alarm, not a party whistle, and not whatever the third thing is meant to be. I have tried each tone when trying to avoid pedestrians, and although it is very loud and gets people's attention, no one has yet linked the noise to the bicycle which is about to hit them, but then why would they. I am not leaving the review to be unkind to the suppplier, but this product was transported, arrived in a lot of both cardboard and plastic packaging, and now even the product itself needs to be recycled. I am disappointed with that level of waste. If you could produce the same product but make it sould like any kind of bicycle bell it would be perfect, and effective as a safety aid for cyclists.

## Features

- 3 TYPES OF SOUNDS: The sound is very loud and clear. There are three models of sounds. After pressing for 3 seconds on the switch, you can change another sound.
- IPX4 WATER-RESISTANT AND SHOCK-RESISTANT: The electric bell is waterproof and you can also use it when it rains. ATTENTION: Do not immerse in water.

### ⭐⭐⭐⭐ Well made but doesn't sound like a bicycle bell.
*by R***R on 12 February 2021*

This electronic buzzer (it doesn't sound like a bicycle bell but more like a car alarm) works well and is easy to use. It is also easy to fit and remove from the bike. and is very compact. It is as loud as a traditional bicycle bell. Unfortunately, a lot of pedestrians on the cycle paths I use here in Milton Keynes don't always recognise the sound as a warning and it's not until I'm up close and sound it again that they respond and realise there's a cyclist behind them. I have resorted to fixing a traditional bell as well. If they can't hear both, there's not much else I can do! I hope that if I use it often enough, it will be recognised as instantly as a normal bell.
