agree that fry outside when possible if you don't have a good exhaust
Also heard if you use Crisco (that white solid shit) it wont smell --as bad (but will kill you due to its unhealthy qualities) I use canola--fairly "healthy"
I have tried both the single, and double size fryers, and I have had better luck with single. The double had more oil, but potentially twice as much food-cooling it even more and it had a smaller wattage heater.... I was running the single and double side by side and single outperformed the double
check the various models and get the highest wattage you can.
I have noticed huge differences in how fast different single models heat up---again, look for high wattage
Get one you can take apart and remove the heating element and put the bowl into sink to clean/dishwasher. trust me.
my secrets:
-------wings. Fresh only- frozen have water added and ice on them---very bad. Also, fry wings for like two min and lift basket--let oil reheat and drop again
-------Homemade fries -- get a fry slicer--soak fries in vinegar/water for 20 min and then fry. drop them into fully hot oil for two min and pull--let reheat fully and finish them off
Smell? no prob---my 60" range hood takes care of the prob
