Product review (1 stars): ***DO NOT BUY***
*****DO NOT BUY****

I ordered one to replace my 15yr old unit. Nothing wrong with the old unit, just upgrading the kitchen. Online reviews seemed okay and couldn't resist the price.

Installed it correctly and the no gas leak detected around connections. Plugged power in and turned it on but it took 5 seconds to light the first and gradually gotten better to around 2 seconds to light up but it was acceptable. Tested all burners and they all worked and thermocouple worked as it should.

Then started the smell of gas. I tested around the connections again, closed the cabinet door for awhile and then did 'sniff' test. No leak in connections. Started sniffing around and found it was coming from the top of the burners. Made sure all the knobs were turned to close. Gas was still leaking. Turned main valve off and the smell stopped. So I have a bad unit and that happens, right?

Contacted Cosmo support and explained the situation to see if anything can be done to avoid return. Maybe adjustment around burner valves or something. They told me it is normal to smell gas from brand new unit and said I should keep using it until it goes away. Wait, what? So I'm supposed to keep the gas line open although there's a definite gas smell coming from it and go to sleep and hope I'm still alive in the morning? So I explained again that the smell is coming out only when the main valve is open to the unit suggesting there's a leak and they now suggested I call an installer to inspect for leaks.

So these guys are first suggesting I keep using the unit and see if the gas smell goes away and then told me to pay someone to troubleshoot their brand new unit for leaks. I wasn't going to pay anyone to tell me something I already knew on a brand new unit. So I did a bubble test directly on the burner orifice and low and behold, bubble started rising slowly from it. I'm done with dealing with these guys. I will be returning it for a full refund.

This unit and model is not Cosmos. This, I find out, is a Chinese made rebranded unit sold by many others. I'm sure I just got the bad unit but I'm upset at their lack of support or even understanding of how dangerous the gas leak is. Don't buy from them or this brand.
