Pros & Cons
Pros
I no longer vote my nails and my anxiety is almost nonexistent. With this i feel focused enough to finish my lesson plans and yet if i need to sleep it also helps me relax after an anxiety-filled day in the classroom.
The pill itself is not a powdery pill, it's a cool looking orange capsule. The bottle has a door/hatch which opens and closes for access. No headache or drowsiness.

Highlights
Quality
I've been taking this for almost a year and i love this product.
My sleep quality and duration is so much better.
For my purpose, combined with the other things i use (cbd supplements and melatonin), they do help.
If you're sensitive to coconut oil, be aware.
Packaging/appearance
I only found some anecdotal assurances that suntheanine was little more than an exercise in branding.
Competitiveness
The little luxuries or improvements, which differentiate it from other caffein pill products are things i really appreciate.
I used jarrow's theanine for a year.
Then they suddenly switched from using suntheanine to generic l-theanine.
I’m now up to 100mg without issue, but may just be something specific to me.

Adding caffeine is great for calm focus too, but don’t over do it.
