I saw these at Bunnies, but noticed the reviews were mostly bad, tipping over, water failing to pass down to the lower tray, blah de blah, so pass them off.
I was buying some sprouting seed from here and decided to get one to try with the fine broccoli seed.
Well it was so good I bought another 2 so we could have 2 units with 6 trays and a daily bounty.
If you insert the trays carefully they don't tip, and we always use 350 to 400 mils to rinse, this ensures that there is enough water level to start the siphoning action.
Just great for the smaller seeds.
