the basic idea, time easy to visualize is good, but not new, and it is certainly not an invention of the "inventor" of the "Time Timer". Various models of inexpensive kitchen timers work according to this principle. To run alone, the implementation, the red disk in the clockwise direction (kitchen timer to run the other way around) does not deserve to call such a price. It's not about the seller of the product, but to the manufacturer. The Time Timer is generally too expensive. One can not speak of a high quality device also. Here everything is made in China, and also the design is primitive. Those who do not necessarily require too soft acoustic signal after the time, should look for alternatives to the Time Timer in the network. Several homemade versions can be found here. I myself have in addition to the Time Timer built a homemade timer, which - except for the beep - works the same as the TT. Price? 6 Euro! And a time of about 30 minutes.
Conclusion: everybody has to decide for themselves ...
