Good Afternoon, I love your product and have been purchasing it for around 10 years. However, I do find that the spray deodorants sometimes run out of pressure which causes the product to stop working. This has happened on many occasions (I always buy a couple at a time so always have a spare) and the last time it happened the can was almost full. Is there a design fault that causes this issue. I really don't want to change my deodorant, but have lost a lot of money on this over the years. I look forward to your response. Many thanks Liz Stanion
