Perfect

They fit well into the designated holder and trap fruit flies as expected.

First, let me start off as saying, this is a great product. In fact, I have two Dynatraps. It catches lots of bugs and keeps the yard mostly bug free. There are two issues with product. One is, the replacement bulbs are a pain to change. You have to go up under trap (fan) and unscrew 4 tiny screws and then inside, bulb is held in place by another screw with a tab. It's not difficult, but you have to change the bulb every 3-4 months,( I use it for 8 months) and the unit is plastic, and taking the screws out several time, does strip them. There needs to be a better design for bulb replacement. Second issue is, the pole. The pole is great for hiding most of the electric cord. However, on one of my traps, (4 years old) the middle plastic bracket snapped off. The electric cord is threaded thru the pole. There is no replacing it and there is no way to feed cord with plug thru the pole. So it is useless. I have a dynatrap that works when plugged in but cannot use it because it is attached to a broken pole. It would be better if there was a way to get the cord with plug out so that I could just hang the Dynatrap on a hook. That said, I do like this product and am buying a new Dynatrap. However, I will be purchasing the one that I can use a sheppard's hook with.

Our bulb had burned out in our Dynatrap, and this worked great to replace it. Lots of small screws on ours to take top off and access the bulb. Not really hard - just seems they could've made it easier since you Will have to change out the bulbs!
