@max2 - Sorry for the delay, been really busy. Unfortunately I only used medium frames, both plastic and wood. I leave all the deeps for the bees. In any event the bees here in NY are about a month behind schedule because of the longer winter/crappy weather.. Will have a review and a video sometime in July. I got the older model from brushy mountain, the newer ones are the same except they come with sturdy legs on it instead of being mounted on the tray. I have mounted mine on a table so it should be a lot more stable than when the guy in the video was using it sitting on top of two supers, which was very wobbly...
