Bought the Mi Cable Storage Box from Xiaomi official online store on Tmall for CN¥45 (S$9.20) (excluding shipping) during their 12/12 sale. The usual price is CN¥49 (S$10).
It is a simple cable storage box that measures 125 x 115 x 309mm.
Unlike Bluelounge CableBox, there are openings at the bottom for better ventilation. A counter-argument is more dust will get in easier.
There is a slit on the cover of the box to let your cable pass through so that you can leave your mobile phone on top of the box while charging.
This ensures the charging wires are as short as possible to make it looks neat. For Bluelounge CableBox, the only way for that to happen is for the cable to exit from either side of the box which is slightly untidy.
