Very dubious company, only had bad experience! I sent a device to this company on January 8th with guarantee coverage, got it back today March 22nd without repair and a form on which it says that the damage was self-inflicted, whereby it is obviously a material defect, I also say that I have a total of 4 these models and never had problems with them! However, very poor service, you kept half of the material and did not send it back, the service MUST be guaranteed! I still wanted to take advantage of the extremely poor customer service that is offered and is automatically disconnected after 5 minutes of waiting! Really a shame such a company ... and I'm curious if consumer protection will do something here ...
