I have 1 sandisk 16gb variant which comes in red and black colour one and other 4gb which comes in white and black colour.
16gb variant product material is really cheap. It too light weight that even can break by little pressure on it. Alsothe transfer speed is not that too good.
My 4gb variant doesn’t work anymore as the steel type usb port get rusted and transfer speed of this variant is wrose.
The service and support is good by sandisk as if the product is under warranty than we have to just courier it to sandisk and they will sent the new product.
