MicroHD hands down.
I had a S10......but that damn deer jumped out while I was coming over a hill and..........OH...you mean an Openbox S10
The Openbox S10 I've read about them overheating. I had one for about 2 weeks and sold it
The Micro is a solid receiver and does more than the S10 does.....and it has US support if there are issues or maybe getting features added.
The Micro was great when it first came out......now its amazing with the minor tweaks that SatelliteAV has added to it
(and I'm not saying that because I did get mine for no cost as a beta tester....and on the grounds I would do an honest review....I'm saying that because this is the 1st receiver in probably 4 years that I didnt want to pull out what little hair I have left while trying to use it)
