That stand looks kind of gimmicky to me. I have some of those single roller stands they work ok. I place it close enough to the out feed table.
For $15 it's ok. Get two if you need the support.
In the past I've made my own using those 5/8" rollers, set in a bearing pad with ears to screw it down. Works great a couple a bucks apiece.
You can have as many as needed to ensure small stock gets support. I just find that stand a bit pricey and well .....
buying some of these offerings today seems ridiculous. Buying a feather board? Why would anyone need to do that? Look in your scrap bin there's plenty in there.
I think we sometimes believe the marketing guys. I could go on but....
well you get it.
I've possibly said too much already isn't there some marketers on this site?
