Worked Great
Used on a minisplit system with a small undetermined leak. The system still had pressure, and had leaked down slowely over several years. Simply attached to the service port, attached gauges, and brought system up to the correct level of 410a through leak stop. Has worked well now for a couple months.

Saved me $3000+
Used this to repair 7 year old mini-split system in a recently purchased house. The AC company wanted over $3000 for a new system, said the system I had couldn't be repaired. Granted it is an inexpensive no-name mini-split system from China with aluminum condenser and evaporator. I understand why they don't repair these - you never know which component will fail next - or when. I bought this, an inexpensive set of gauges, and a bottle of R410 and had it fixed in a few hours for a few hundred dollars. That includes the time spent watching YouTube videos. Over a year later and it still going strong.

Satisfied
I used this product after being unable to find the leak in my ac mini split. It worked as described and I have not had a leak since.
