Product review (5 stars): Took less than 10 minutes to fix my fridge. ...
Took less than 10 minutes to fix my fridge.  The tube is small enough it should fit just about any brand.

I tried a heat gun and melted some plastic, I tried a hair dryer with no success.  Not sure if this is just a normal syringe with some clever marketing, but it wasn't much more than the other ones.  Only time will tell when it'll freeze again but I'll be ready next time!
