These Wico Sticks any good?

I’m looking for good sticks for a MAME setup. I know people love Wicos for old-school action but I always see the leaf-switch ones. Then I saw these on EBay:

Anyone know if these are good sticks? Not really for fighters of course, but just MAME action in general. Thanks in advance.

it is wico microswitch joystick
only good is Wico leaf switch and Wico Conical with improved actuator
wico mikroswitch and first wico Conical have crap actuator no floating, but wico microswitch work better
for MAME is OK
for Fighters not good choice:P

You have info/pics of this on your website kowal?
