I ordered this product and received it broken on Friday. When I emailed them I received a response in less than 30 minutes and in an hour they shipped me a new one. Just got the new today (Monday) and it looks great.
My first diffuser and I love it. I use this on a Rena canister filter and provides ample co2 mist for the aquascape. The price was perfect so I purchased two units to rotate between cleanings. My kids think it looks so cool lol!
