Question about electro-gen thermo fogger

Hello, I am new to this forum and am excited about everything I have read and seen.I am in need of some help and would be very grateful for any and all input. I am looking into purchasing a "Electro-Gen Thermal Fogger" to use for odor removal in cars. I would be using this for mainly cigarette smoke, and mildew smell. Does anyone have any experience or knowledge about how effective these foggers are? Would you recommend something else? I am open to all opinions and thank you again for ANY and ALL help!

I apologize. I wasn't sure how the forums worked... I thought if I posted in two places I would get more wide variety of opinions and input. I was not trying to cause a problem or hassle and I sincerely apologize if I did.
