I have seed spoons. They were a free gift from some seed company when I ordered seeds. They work well, but I've only used them when I have only a few seeds and they're too tiny to handle. In such a case they work very well.

I've tried the first two at this link.

The second syringe type thing I found pretty useless. The first one wasn't totally useless, but it didn't impress me either. My husband bought both for me.
I just used the links for illustration, I'm not recommending the companies. I was just looking for illustrations.
Most of the time I just sprinkle the seeds over the soil with my hands. If I want more precision with tiny seeds, I use seed spoons.
