In early March 2015, I acquired by Amazon inforad a CI, commissioning reports to the parcour fighter !!! - Nowadays; I am 25 attempts telephone contacts (answer: "all our line are busy, your call again") - I tried contact by email, I received a totally inadequate answer to my question !!!! - I strongly discourages this type of product. This is a company that is totally lacking in seriousness and totally mocks its customers !!!!
