I haven't put it up for sale yet, as we are developing the Android app part for the newly integrated Bluetooth LE part. Its necessary for parameter configuration. I am putting out the first intro video today. Will post a link here soon once i do that.
I agree that the data is scattered all over social networks. 
But, the information of our products which are ready are put on the store https://www.valetron.com/store in the form of spec sheets and youtube intro videos.
Meanwhile can you help me understand what would you like to test or how would you like to evaluate the device, are you interested in using it as end product or for development and experimentation ?

How can I order an instance for tests. I'm from Ukraine. It is also interesting where you can see a detailed description of the project and is there a main page on the Internet? I have been following the project for a long time, but all the information is very scattered across various social networks on the Internet.

I have posted a first intro video, Please check for basic details.
