I have had my set for almost a year now and I'll say this; this setup does not have all of the bells and whistles that an R12i has, however an R12 is also about 8 times the price. What you get with this setup is an incredible value and it can do the vast majority things. i have used mine to run static and set up control which i then ran through OPUS and got a bout 1cm RMS which is fine for my application. If you plan on doing topo survey, you should know that the provided survey software does not seem to support TMOSS survey style, or at least i have not been able to get it to work correctly. This software can, however, provide mock locations to the android OS which enables me to use a base and rover setup with Qfield when doing GIS work. One thing i would like to see from the manufacture is that the Unit should ship with an External power cable with gator clips on the leads to use with a car battery. This unit will quickly use all of the Battery when using the internal radio. You can use the USB-C port on the back of the receiver to charge while it's in use, but this doesn't not seem super sturdy to have a long cable hanging and swaying in the wind. I think that this will probably have issues in the future. in addition, it offers a path for water ingress. I get a couple miles of range at most when using in remote areas of my state with wide open spaces and i get about 3000 feet at most when i am in the city, less than that if there is a lot of radio interference. I would like the see the manufacture offer a comprehensive external radio kit for this unit that comes with all needed cables and connectors as well as the correct antenna and mast for it. As an alternative, in future iterations of the product, the manufacture could integrate a NTRIP caster function to the units similar the way that can be done on the R10 and R12i. Customer service has been very responsive and helped me out on a couple of minor issues. Overall, this has been a great purchase for the money and there is not much to complain about.

Los equipos llegaron con todos los accesorios que indica, solo que Amazon tardó casi dos meses en hacer el envío y la entrega. Los equipos se ven de buena calidad y vienen en su estuche duro para almacenamiento. He realizado pruebas de levantamientos con los receptores y son fáciles de configurar. Las consultas a soporte me han contestado rápido. Hasta el momento podría recomendar estos equipos por su calidad y precio accesible.

muy satisfecho con la compra el servicio de posventa me ha estado guiando en todo momento cada ves que lo necesito.
