Arrived as ordered. Have not used it yet. Says must draw a refrigerant down to inject. Guess you cannot inject with refrigerant pressure?

Hope I don't need to use it, but if I had it when installing the unit I would have used it as a precaution . Love my minisplit

I used this according to instructions and after one week, the mini-split is still pumping out cold air. Hopefully the leak got plugged.

Excellent customer service. Knowledgable and very helpful. They followed up to make sure I knew how to work with the product I was purchasing.

NOT SURE IF ITS A GREAT DEAL OR NOT. HAD PREVIOUSLY ORDERED 1 IN AN EARLIER SHIPMENT. USED IT ABOUT 9 MONTHS LATER - SEEMS TO HAVE DONE THE TRICK. ORDERED THESE 2 JUST IN CASE. HOPE I NEVER HAVE TO USE THEM.

ALL MY DEALINGS (EXCEPT 1) WITH HIGH SEER HAVE BEEN EXCELLENT. THE ONLY PROBLEM I HAD WAS WITH THE UNIT THAT HAD A 33' LINE SET. I WAS NOT AWARE (UNTIL I SPOKE WITH TECH SUPPORT) THAT THE UNIT COULD NOT BE PRE-LOADED WITH ENOUGH COOLANT FOR THE 33' LINE SET AND ADDITIONAL COOLANT HAS TO BE ADDED AFTER INSTALLATION. AFTER USING THE FIRST LEAK STOP I ORDERED WITH THE MINI SPLIT ORDER, RECHECKING PRESSURE AND FOR LEAKS AND RECHARGING THE SYSTEM WITH THE PROPER AMOUNT OF COOLANT ALL SEEMS TO BE WORKING PROPERLY.

The check valve bead somehow popped out of the fitting I needed to use. I didn't realize this at the time and it blew out the back. HighSeer took care of me and sent a new one out. This time I'll know to check for the check valve bead in the nozzle and a few extra tips. The customer service at HighSeer/Pioneer is great!

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
