Easy to build, flimsy construction, but works a treat. I use it in a trug that is just the right size, I can load it up on the floor, sit on a chair and turn it to sieve. Trick is to just turn it anticlockwise so the knob does not unscrew. No bother with it missing the edges, just push down and turn the handle, so, so much easier than shaking a sieve, a pleasure to use. My compost was damp and had lumps in it but it handled it well. Recommend.
