## Questions & Answers

**Q: Can you replace the bulbs**
A: Yes

**Q: How do you get in touch with the seller? Recieved mine yesterday but only one bulb works**
A: If it's fulfilled by Amazon, they should help you.

**Q: Does it work in the daytime?  Thank you**
A: Yes it does. It plugs in and has a on/off toggle switch. So it’s down to the user how long you want on for.

**Q: Replacment bulbs for this item**
A: It's really simple.  Just undo one side of the the cage by the screws on top of the  appliance.  (Make sure its the side directly in front of the bulbs and not the side with the 'zapper' part between the bulb and cage.)

The bulbs then just simply lift out and replaced the same way.  It really is that simple. :-)

## Customer Reviews

### ⭐⭐⭐⭐⭐ Unbelievable product
*by A***R on 2 November 2023*

Ordered this fly zapper a few days ago after getting infested with blue bottles in our cottage, spent hours the first night going round with the hoover sucking them up when they landed and again on the second night.Got fed up and ordered this fly zapper and waited with anticipation for it to arrive which it did as described.So un boxedit and it and placed it up high and within a few minutes I hired my first zap then another zap and another zap and so on.Worked really well and so satisfying to hear the zap and pop lol.

### ⭐⭐⭐⭐⭐ Highly Recommended
*by M***N on 22 May 2020*

I've now bought three of these, they are effective, gently frying flying pests. The unit is sturdy, the tray is secure, looks smart, and chain is strong.After my first one, I made the mistake of buying a slightly more expensive unit, which was flimsy and sounded more like firework bangers when it goes off.I've sent that back and got 2 more of these babies. Highly recommended.

### ⭐⭐⭐⭐⭐ Works well on house flies but power cable a bit short
*by E***H on 25 June 2022*

I've had similar ones before and they've never been very effective against flies. This one however attracts and zaps them really well - very impressed. It's a large unit but built well and feels solid. The only issue is the power lead is very short only about 1.5m so I've had to use an extension to plug it in. Located in the kitchen.
