Review on 🔧 Efficient Spring Lock Coupling Tools for Air Conditioner Systems - Powerbuilt 641290 by Committed Schmidt

These were recently used on a Nissan Quest '99 minivan. These tools did the job very well and easily. I was able to disconnect the lines to replace the o-rings and battery. I just followed the instruction manual on how to use it. I also used them in a 2001 Nissan Quest for the same purpose. I no longer need them, so I can't comment on durability. For me they worked great and saved a lot of money at the store.
