## Before you buy

The listing's controls, corded-electric power and 50-gram weight appear alongside a small syringe additive, so confirm these detail fields describe the selected item before relying on them.

## In the box

- 1/4 SAE adapter (Included)
- 5/16 SAE adapter (Included)
- R134a adapter (Included)

## A good fit for

- Vehicle A/C owners or technicians considering an additive for a compatible system with suspected oil fouling.
- AC/R users whose system is within the stated 21 kW dosing limit and does not use ammonia refrigerant.

## Less suited to

- Systems using ammonia refrigerant R717, which the manufacturer excludes.
- Buyers seeking a leak-stop treatment. This product is described as a performance additive, not a leak sealant.

## Customer feedback

Aggregate customer ratings are mixed rather than clearly favourable, with a substantial share at both the highest and lowest star levels. That spread does not explain why customers rated it as they did. Buyers should weigh it against their specific need for the stated oil-fouling treatment and the system's compatibility and dose limits.
