Have got several different sprouters mostly from bootfairs or charity shops. Find the square tiered one good but this one which I had for Christmas a few years ago is the most convenient as you don`t need to rinse every day. Sometimes the sprouts do get a bit matted so I give them a rinse and separate them after 4 or 5 days.
I think it`s on E bay as well.
