Tchibo is annoying many sectors with products from its own TCM brand that look functional and attract customers with low prices. The latest product on offer in the coffee shops is a bike computer with wireless transmission and solar cells, which, according to the instructions, are supposed to help save battery power. However, the computer does not run on solar power alone. All common bike functions are on board, operation and installation using cable ties are extremely simple and the operating instructions are exemplary. The device itself is a little clunky compared to branded computers, only the upper half of the housing is painted - the lower half shines in plastic white. The speed display reacts somewhat sluggishly.
PLUS: good value, easy installation, very good operating instructions
MINUS: cheap optics
