Great product for the price. Been using it for a little over a year and had no issues with any parts leaking. Most Complaints are user error. It only gets as cold as the water you use. I like to put the bag in my garage freezer for a few hours to get a layer of ice then break it and drop the pump in. Pad is a little awkward to get in the right spot but ive learned that flipping it "upside down" works great to get the front of your knee and running tube behind your neck positions it perfectly for elbow use.
