Big Co2 bubbles coming out from the side of the disc. I tried to fix it by using waterproof glue but it doesnt solve the problem.I used it for just 2 days and paid around $24. A waste of money. I went back using a glass diffuser for $9 and works better.Not worth even for just 1 STAR Rating. Dont buy it.
