UHD freeview satellite receiver choices

[1sobriquet]

Thus far, for 2 yrs that is, have been enjoying my Ferguson Ariva 4K combo. Latest factory FW is working well & GUI is better. But, blind scan, which is a must for NA, is not very thorough. Some muxes must still be manually entered. Here in NA ITC feed muxes come & go quickly both in C-band & Ku-band.
Have a DM800HDse which sees some use. Looking for an E2 stb with more capabilities so have purchased a Formuler F1 from an Irish ebay seller(same source as my Ferguson 4K.)

Here in NA there is a "vendor", and I use the term loosely, proffering Zgemma H7s boxes with lofty promises of performance. Yet there is also feedback posted in other forums elsewhere denying its capabilities.
Is there anyone here with H7s experience who can speak to this?
I'm sure there are other, perhaps better, sources for this stb & would like some input.
With much thanks.

Formuler F1 arrived by mail yesterday. Hooked it up to C-band dish for testing. Navigating the menus found many similarities to my DM800HDse rev1, which is great. Satellite arc includes all of NA satellites which thankfully saves a lot of work.
No discernable blind scan as delivered but will explore further here for 'augmentations'. A few GSODs but I have to believe that was my error - inputting remote commands too quickly in setup. Confuse-a-cat or stunt-a-stoat.

Will abandon idea of Zgemma H7S now. Don't want to experience what others have with that vendor that has no product phone support nor a physical address yet operates a Canadian forum.
