Rarely have I been so disappointed by a product like this: - The "bell" is much larger and bulkier than the (distorted) Product image (see my photos) The AAA batteries are put into cross - which shows that the bell is very broad. - The processing and the material is cheaper than that from OB eggs. - The volume is indeed "beautiful" high but so loud that I do as cyclists ears hurt. It may be that they are therefore widely heard, but I can not keep me while driving ears. Whether that's at all approved I bezweiffle because the Highway Code prescribes a maximum volume which is significantly exceeded safe. - The "push buttons" is a cheap plastic tab, sharp-edged and slightly brittle. An ordinary button would be better. - The attachment is Low to plastic and can be turned away from the side of the bell. She hangs only with a tiny metal screw for connection to the housing everything. Any bets: the 2nd curb the thing flying away. - The battery cover is made with a 1.5 mm self-tapping screw to. For me this was so firmly in the plastic in it, that they are already at the first opening (not Close!) Is canceled. [Note .: reason for my return.] - The ring tone sounds like birdsong. Is certainly funny, ridiculous here in China.
