Maybe my favorite purchase ever-- we used to have one of those "freeze the basin" ice cream makers, and it very rarely worked well for us.  But we like making no sugar ice cream with fresh cream, so we thought that we would try this.  I wasn't sure how it would work in our always-warm-California-kitchen, but it is AMAZING.  Sometimes I get lazy and don't even bother to cool down the mix once I've cooked it on the stove, and this STILL turns it into ice cream quickly and easily.  I typically make one or two servings of ice cream several times per week, and I can usually get it to the consistency that I want in under 20 minutes.  I've had this for almost six months now, and it's still working great-- no issues at all!
