Product review (1 stars): Not a project you want to tackle.
I bought this product. Found it easy to assemble and very easy to install. Only took one person to install. Electrical was very easy as it is just a plug. Like pluging in any other appliance. The stainless is very sharp. Use gloves and long sleeves when installing. Maybe a neck and face guard too. Being as you must look over the top of said stainless chimney.
Fan works but is a bit loud. Mounting the charcoal filters is a bit of a dirty job. Mounts to both sides of blower housing. Charcoal is black and its all over the cartridge. Now down to the nitty gritty. The lighting system is bad. Not the lights themselves. Don't bother hunting down new replacement lights yet. It may be a waste of your time and energy. You will end up very angry with new lights because the lights still don't work  and or strob. Dirty power from the transformer installed on the microprocessor. This will take either new microprocessor board( as if that may work) might not! Best thing would be to gut it and install new simpler direct system. Leave the wiring just gut the processor. Have fun with that one! Switches are microprocessor linked  as well. Need a real diagram of wiring so as to be able to use this without replacing switches. God help you. I hope you have one of those kids or are one of those kids that love to disassemble and remake. Not worth the money! Walk away now! Or have a product like a harley. Loud and you have to rebuild it.
