Has anyone used VMGate from Startel International or FusionGate in production?

I'm evaluating it as an alternative to Huawei dongles + chan_dongle or hardware GSM gateways (Dinstar, GoIP).
Interested in:
call quality
stability
SIM rotation
SIP interoperability with Asterisk
long-term support
any hidden limitations
Looking for real-world experience, not vendor information.

For some reason, they have two websites, which struck me as suspicious:

FusionGate - Transform Android Phones into Professional GSM Gateways

FusionGate transforms Samsung Android devices into professional GSM termination gateways. Software-based VoIP to GSM bridge solution. $99 license vs €1,200-€2,000 hardware.

VMGate | GSM Termination, VoIP Termination & Android Gateway Software

VMGate: Professional GSM termination, VoIP termination, and Android gateway software. Transform Samsung phones into GSMBox systems for Android termination and SIM card termination. Software-based Android GSMbox alternative to expensive hardware.

They are two different companies doing the same thing. Not sure why that would be suspicious. What is suspicious to me is the same thing they offer is fraud based voice services. So good luck with that.

I'm always suspicious of people who join and post junk like this on the first message. It is likely a scam advertisement.

That was my first impression as well...

Well, this isn't really an ad—it's more like a bad review.
I just don't want to buy something that's unclear; not only will it probably not work, but it might also cause some kind of problem.
I'd like to know if I can trust this with my SIM cards.
