Love the Kiss pro we have at league. Less then 5% SDTM from the head. It used to be 50/50 but what ever the operator did works great now. We get more drains out of the pops to right outlane then from the head. Still very fun to play. Wouldn't mind owning one but can't buy them all.
Simple fact. If you're buying NIB do your research. There will always be many things that needs adjusted. However if you know what to look for they are minor.
