Mine is not opening good, I have to press button many times, and its only opening a little bit and its hard to grab the cover to open. I have to use my credit card sometimes to pitch it out. Do you have the same problem?

 

yeah this happened to me once. i cleaned it and it hasnt happened since

 

Good advice to keep it clean as there is no manual release that I know about.

What did you use to clean it???
