Query: a total piece of junk

the mosquito magnet is a collosal mistake unless you feel that $30 per mosquito is a good deal. it would be a better result to hire a service to come monthly for the cost of your octenol and propane alone. let alone the $1000 for the unit. now that it is broken, they want $395 to fix it. they will coddle you along until the warranty expires saying that you have the wrong type of mosquito or some such rubbish. do not buy these units.
