We bought this as an alternative to the propane traps (which I hear are expensive to operate and aren't the most effective.) We love the DynaTrap! At first, it was hard to find a good spot for it (it can't be in direct rain and needs to be hung ideally, 6 ft. off the ground) but once we switched it on, it was like magic! The instructions say to empty it once a week, however, we are getting so many bugs, we are emptying it about 2-3 times a week. We bought two of them, one for each side of our house and now, when we are outside around dusk, we rarely get bitten! I highly recommend this product.

I was a bit apprehensive when I bought 2 of these off of clearance (when Sharper Image had them for $39.95 through Amazon). I had been looking at a Mosquito Magnet for about $300 when I figured these were worth a try. I installed both in my backyard (about .25 acres) and turned them on, so no problem with installation and set-up. The key is to have a covered, darkish location to set them up.

I started them in the beginning of May and cleaned them about 2-3 weeks later and pulled a baseball sized lump of dead mosquitoes out of one, and a golf sized lump out of the other! My wife and I didn't realize how many mosquitoes were out, even this early in the season! It's been great to go outside without slathering myself or the kids with bug repellant.

The best of all is the low cost of use. The bulbs last 4 months (according to the man'f) and have a $10 replacement cost... even running it 24/7, the unit takes about 20W of electricity an hour... maybe a $5 addition to my electric bill a month. Compared to the Mosquito Magnet which uses a tank of propane every 3 weeks and needs 2 different types of lures (and also uses a few bucks in electricity a month), the month costs are a ton less with the DynaTrap.

My only complaint (still not enough to knock this down to a 4) is that there are a few live bugs to deal with when cleaning out the unit. Usually these bugs are so out of it though, they aren't eager to bite you! Overall, a great product!

This product seems to work great. we heard about this from our daughter in green bay wi. She read about it in the paper. She has a woodsy backyard and loves the product. We had a mosquito magnet for the last two years and it was expensive and a hassle to run. My husband was the only one that could make it work. We have orderded from sharper image before and had excellent results.
