Hello, I do not know if anyone knows the new eweat dmp20 and dmp50 and if there are any reviews out there about them and what opinion do you have about said devices that in terms of hardware I think they are quite similar to the bune hd max vision and dune hd ultra vision respectively, in the software section I have my doubts about troubleshooting updates and such. The fact is that being similar they cost less but I do not know if it is good or not.
