Anyone using these?

I have a tandem with a Rohloff, which means using a 22.2mm grip shifter. But I’ve never been convinced by flat bars on it (it’s used for road and gravel, rarely anything more challenging than a bridleway). So this might be ideal.

How are the hand positions on it, though? It seems like there’s just the one on the drops plus maybe one in the tops. Not sure I can visualise a hoods position, but maybe there’s some trick with mounting some bar ends or similar up near the bend?

Also I’m not aware of any alternatives (cheaper or differently shaped); are there any?
