I was using a can of Bloxygen and it wasn't working. I had used it 29 times and was upset that I had a quart of Waterlox that needed something to keep it from setting up in the can. I e-mailed the company and received a response that day. They said the can probably had a faulty valve and they sent me a new can, which I received within 3 days. This is excellent customer service. I prefer Bloxygen over StopLoss bags because of the ease of use.
