Pros: adjustable water pressure
I love this diaper sprayer. It's made cloth diapering so much easier.
It's easy to install. It has held up for around a year and a half now and I believe it'll hold up for a long while more. If it ever does fail me, I'll get another even if I'm not cloth diapering anymore because it is so convenient having a spray nozzle on the toilet. I didn't know what I was missing.
I cloth diapered without the sprayer for almost 2 years off and on and it was a pain to dunk and swish in my opinion but doable if you have to. I'd just much rather have the diaper sprayer.
It works really well for cleaning up other things as well - examples: puke, food, buckets, etc.
