I have used it once and it worked great. The seal between the two buckets is pretty decent when its filled up with comb while it drains. I used two nylon bags, one in the top bucket and one pulled up on the bottom bucket. The bottom filter definitely helped strain it. However, the holes that were drilled on the top bucket left a lot of small plastic shavings still hanging on around the drilled holes. I used a light torch to remove the plastic shards which cleaned up the bucket real nice and made it smooth. The seal on the bottom works great. A little pricey for what its worth, but this is by far the cheapest method to harvest your honey and separate your wax. Would definitely recommend.
