Review on Simple Modern Cocktail Martini Shaker by Shannon Baroody

At first I really liked this shaker because it has excellent sound insulation, nice design (I chose marble), the dimensions in the lid are convenient. However, after about 6 weeks of use, the lid started leaking excessively to the point of being unusable. I've tried making sure the rubber o-rings are properly positioned, clean, etc. but nothing will fix the leak problem. Unfortunately this started after the return window so I am asking for a replacement or refund as the leaking issue is quite serious.
