BUT:
In the product description on Amazon and on the Homapage the manufacturer is (on 12/09/2014):
"Makes traveling for fun and excitement: The cheerful Pram Rattle function."
Unfortunately, this chain do not rattle.
The first chain we complained at Amazon (because I still believed in a product defect) and soon we got the replacement. Unfortunately, this also does not rattle.
Then I Sigikid contacted directly. Statement is true, the carriage chain has no rattle function. We have changed the product and the last 2 product shipments no longer rattle.
When asked why the product is still advertised with rattle function (even on the Sigikid Homepage) I received no clear statement.
From a company like Sigikid I expect more.
