The lip is not high enough to totally negate the puddle on the Northstar figures I got these for. What works really well is a cheap orbital sander. I haven't experimented with finer and coarser grit, but either one should work. Anyway, you grind about a millimeter off the bottom of the puddle, and then you plastic cement the rest of it right into these. The lip is high enough that you don't have to totally grind away the puddle and risk snapping a leg off. I've actually had the legs snap off of minis even from trying to take their base off with clippers, because the cutting jaw does impart some lateral force as it bites in. So! Ten or twenty seconds with the sander plus one of these is the best solution. Note that if for some reason you have a resin mini with a puddle base, DO NOT sand it without a much more serious respirator than you would use for plastic.
I do think the name isn't great. "Dual Use" bases is sorta silly, there's no reason to get these and then use them lip-down. Just call it a Bucket Base - that's what I've been doing informally, and I think it's more descriptive.
Pictured is an unpainted mini stuck on one of these bases. I put some black stuff down to fill in the bucket and sprinkled some snow over that. Looks good, can't complain. And the price is right.
