ZeroR® Permafrost for R1234YF AC Systems | Performance Booster | 5 Cans + 24" HD Can Tap Gauge

Easy to use and a good value. It came with a gauge so a complete system for adding freon.

Baught refrigerant in the past from different company’s but this product beats em ice cold for sure highly recomend

Restored my AC performance. Application hose that comes in kit was very easy to read and know when you have put enough freon in without overcharging your unit. Although this type of freon is a little pricey compared with 134a, you don't use as much. Cars with this type of freon generally have a smaller capacity. Based on this, although it is higher in price, the fact that you don't use a much offsets the price difference.

This is a rip off. The cans are extremely light and almost empty. And they charge you additional shipping fee for returning them. Stay away from this product until they start adding enough Freon in the cans.

It works. Car is cooling It came with attachments also

Just as described

Very good

Tubing needs to be longer. Other than that no issues.
