Knackered Knees
They work quite well,have used them for quite some time now. If your doing a large floor though your fingers will get really really sore from pushing the wedges into the slots and pulling up tight. I would also like to see the legs that go under the tile be made straight, rather than having a slight radius which forces the tile to sit higher, then you add your wedge and apply pressure to force the legs straight. Breaking off the legs the next day after the glue has set is really easy.
