No instructions for how to replace this bulb and it was not fun. You should be able to reach through the openings to remove the protective shield and remove the bulb, but that is just not possible. I tried multiple times. Instead, I had to remove the top shell (8 tiny sheet metal screws) and then top plate (3 more tiny screws). Then I had to remove the bulb shield (1 screw) and then the bulb retainer screws (2 more screws). And then, unable to reach the bulb housing, I tugged on the bulb, only to have it fall apart in my hand (see photo). TERRIBLE design. It took me 8 minutes to disassemble with a power screw driver and 15 to put it back together. The top lid is very difficult to align. NOTE: Mark the top cover with some white paint or white out, so you know how to realign it. Terrible design. And one the second unit, I tried to lower the bulb assembly from the top (4 more screws), only to have the connecting wires come off !? I have several of each of the smaller units and they aren't much fun to change out the bulb, but this one was by far the most difficult. At least use thumb screws and find a way to change the bulb without removing the top assemply. That's just wrong and who wants to do that every 41 days ?

The picture is what I saw when I opened the too small of a box for my order of bulbs. Only *1 bulb out of a 2 bulb pkg. was delivered; packaging from bulbs disassembled & separated from bulb, so the remaining bulb was unprotected; bulb was placed diagonolly so it just fit--no wrapping around the bulb! I have ordered the same item before, several times, and things were packed extremely well! AND I got 2 bulbs in a 2 bulb pkg. before, unopened, as a customer would expect! When I called, I was told the item would be reordered for me and I'd get an email to that effect. I received an email saying I'd get a refund because I had never received the item. (I did get part of it, but am not even sure it works because of precarious packing.)

We have, well had lol, quite a mosquito problem on our front porch and saw this tiny Dynatrap and thought 'what the hell why not'. It actually worked better than I expected! Mind you this is on a pretty small not-very-open front porch, like enough seating for 3, and it was hung on the ceiling which is where all the mosquitos were too. The picture is about 2 days of it running 24/7. The build quality does honestly look kinda cheap, but I haven't had any problems with anything mechanically or what-not, and the bottom casing that holds the bugs that clicks onto the rest of the trap does feel solid. No complaints so far! I honestly would not expect this kind of result on average, but we had what looked like 100 or maybe more mosquitos condensed onto the front porch, but it still worked so dang I'm all for that!
