The auto sprouter is a motorised sprouter. You fill the base with water, sprouts added
to the trays, dividers placed in and tubes with a sprinkler on the top suck the water & sprinkles it every 50 mins for 10 mins until your seeds sprout. You still need to change the bases water regularly as it can get very dirty & smelly. There is no pre rinse of sprouts involved, but if you want you can pre rinse them to keep the water cleaner for longer.
I found the sprouting to be quite successful, especially with the harder to sprout seeds and waxy seeds such as flax and chia, both which I have found great difficulty in sprouting other ways. The motor is very quiet and the base doesn’t seem to get hot or even warm from long periods of running so you can leave it on continually. Mine was new and not working and when I emailed the makers they were more than happy to send a new sprouter to me, no questions asked, making me think there may have been a common fault with them. I kept all the bits off the sprouter that didn’t work and added an extra tower to it so I could get more sprouts. The pump was powerful enough to reach the top and spray.
The sprouter is over all good however it is quite a large item, taking up a lot of room and sprouts less seed than other sprouters I have.
