아산화질소

It handled a solid few hours of light work without any issues, and the standard canister felt better made than some cheaper ones I've tried. No complaints, it does exactly what you need.

Used it for a longer procedure and the gas flowed consistently, which kept me relaxed without any dizziness afterward. The valve adjustment is smooth and precise, making it easy to control the dosage. Exactly what I needed for a stress-free experience.

It worked well for the minor dental procedure I had, with the effects wearing off pretty quickly once they stopped the flow. The only downside was a slight headache afterwards, but it did the job.
