U.S. Solid 500ml (16oz.) Liquid Nitrogen (LN2) Sprayer - Freeze Treatment Instrument Unit with 9 Freeze Heads, Empty Tank

Will not hold nitrogen. Leaks, does not have appropriate caps, and has a small pin hole in the side of the nozzle. Absolute garbage.

I have not yet used this device. Appears to be well-made. Arrived exactly as described.

I thought this was the same thing my Dermatologist used, but it doesn't dispense the gas.

Not well made. Had to send back.

Do not buy. Leaks at the seal. Inferior quality for the price.

Is a good product at a convenient price. Works very well for me....

I bought this with the assumption that it was a "sprayer" as labeled. Only one tip accommodates spray function. Remaining tips are all solid. No on/off spray function. I would have returned item except I discovered deficiency after return date.

I was hoping it would have a lever to start and stop the spray, but you can control the spray with a little screw. The escape valve is always open, which is good, limiting pressure buildup with the liquid nitrogen.
