## Customer Reviews

### ⭐⭐⭐⭐⭐ Loud
*by H***O on 27 May 2024*

Loud product but with only a few options of differing noises one of which makes it sound like a toy. I think a loud electric ding should have been included but the whistle sound is the only serious noise it makes. That said; easy to fit, easy to use, easy to charge.

### ⭐ Doesn't ring like a bicycle bell
*by G***C on 20 July 2021*

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.

### ⭐⭐⭐ It's ok nowt special huh
*by A***R on 8 May 2024*

I've had this a couple of months now used most days. The first mode (whistle) get people looking in the fields either side of track for someone training a dog or something and not what's arriving from behind them. The second mode gets people looking in tree's and bushes again not what's arriving from behind one lady thought it was some kind of bird tweeting in the tree. Third mode is what it is laughable, people just can not associate these noises with a bike. Could do with being louder I think when the battery runs out I'll go back to the good old bell as this is what people associate with a bike.
