I use one...it's o-k...good for doubling...i shim the bridge up to get it to what I would term very low (jazzish) action for a bass fiddle...with careful eq'ing you can get an o-k slap sound out of it. Fits in the Saturn real easy too.
Not sure why, but it sounds absolutely wonderful in the studio.
It's indestructible onstage...cheap...sounds o-k...easier to amplify than the real thing...uses 35 inch bass strings...I have year-old slinkies on mine, and they sound good.
The bad: tuners suck (only bass I've ever contemplated replacing tuners on)...piezo tone is only so-so...I use an outboard fishman B 2 for preamp, with a stompbox graphic EQ. (Later models of this were made without the internal pre-amp.) Certain frequencies have to be eliminated in order to slap, or they'll tear your head off (high mids tend to be strident). That's why the stompbox eq.
We do lots of oldies rock and roll, and play almost every weekend. It does the job (both pizz. and slap), but if I were wealthier I would probably use something else. It's kind of a poor man's Azola Gypsy, or Kydd Bass, I guess.
Hope this helps...
