Review: Great product - Purchased this product as I used to have one in Australia and they work well. The cartridges aren’t cheap to replace but if you remember to turn off the machine they will last 2/3 evenings. They do keep the mosquitos away once it warm up. Certainly worth buying so you can enjoy being outside in the evening.

## Questions & Answers

**Q: How much does it weigh?**
A: 180 grams

**Q: Can I take this on a plane**
A: I guess the answer would be yes because the solution cartridge can be removed and put in a clear plastic bag with other liquids which are less than 100ml

**Q: Hi - can the gas cartridges be refilled? - they look like they could be (using standard lighter refuelling cans?).**
A: Yes they can, but only if you remove part of the valve assembly first. There are youtube videos that can guide you.

**Q: Does this kill Gnats or just keep them away? UK**
A: it just keeps them away I think

Used for whole season. And I have no bites. Great better design than older ones that broke easily . Easy to use. But gas cartridges are a bit pricey.
