Has anyone used Robustel routers?

[Gnilias]

Well, I thought I'd hit on the solution for my on board comms with a Teltonika RUTX50 paired with either a Poynting EPNT-4 or a Qu-spot antenna and housing. But the comms store that I am buying from says that the RUTX50 won't work in the US so they have suggested the Robustel R5020 router in a Qu wireless or Poynting housing instead. The pricing and global coverage of the Robustel R5020 is fine but I can't find any forums or user groups for them online. Has anyone here used a Robustel router? Is it any good? would you recommend it?

And regarding the choice between Qu wireless and Poynting, I know Poynting have a very good name. The trade off seems to be that Poynting have a better reputation but the Qu wireless enclosure / antenna would be perfectly paired to the router. Which would you choose?

Thanks!
