I have no experience but by looking on amiga.resource.cx its not got many features.
essentially its a 15bit 32k colour card - and this is only while its screen dimension is no larger than 800x600 - any higher and you are limmited to 256 colours. What also is pretty poor - is that while the AGA has a 24bit pattlet (thats 256 colours from 16Million) the Domino only had 256 colours from 32,000 (well 32,768 to be exact)
I would say that there are three plus points for this card -
1. Supported by P96
2. Supported by CyberGraphix
3. Has VGA Pass through
Now, I notice that the card has a socket for a monitor switcher - this I suspect means that card can not "Auto Switch" dispite the pass-though VGA header
All in all there are much better card to get - but if you are happy with an 800x600 32K colour workbench and you are happy to press a button to change video-sources for when playing games - then this card might be for you.
There's actually two plusses on this card. The usually low buying price, due to the "less-wanted" situation, and the fact that it is NetBSD and AMIX compatible. Other than that, it's actually an ISA pc card, plugged as a daughterboard to it's main pcb. Something like the X-Surf style..
