They are awesome, light and work well, plus for me the shape is great. I guess if you are part of 'Club Grafton minimum' they are low-rent, but they work, so they have at least that over some of the chi-chi brands.
They where the bees knees of levers for the lightweight power and cheap turn of the 90s around these parts. Cooler than the SS7.
Iirc where powerful due to short cable pull compared to others.
Often used with shimano super low profile DX/xt of the day and 987s
Generally removed from use when shimano servowave lever became affordable in some way. Just no where near as good as them.
