My kids and I love these clickers, they are essential in tropical Queensland. They last years, are no mess, work quickly and just should be in everyone's home. Heaps better than creams and so convenient.

Must get Clicker on to bite quickly and it disappears altogether. SOOV Bite cream as a backup. I suffer terribly from bites, am allergic to saliva. Always have on hand.

Works tried everything else this is worth the money. Totally recommend to all sensitive mossie bite reactors. won’t use any creams or spray again. Swelling went down within 4 hours.

Sorry, this doesn’t do anything. Used it as described and no relief. Clicked away a hundred more times. Still no relief! Waste of twenty bucks and thirty words. Thirty words!

the clicker is not only good for mosquitoes it is great for ant bites and wasps. It is also fantastic for leaches!!! If you apply after you remove the leach you never get any of the 2 week itching. I have also used it on ticks with good results, but you need to do 10-15 clicks a couple of times in the first day after removing the tick.
maree

I've suffered from skin problems for some 16 months now - it mostly starts with an itch. I grabbed one of these from the local chemist on a whim (after trying "everything else") and am VERY happy with it. It won't solve every outbreak - and no-one seems to stock them "on the street" anymore - but "it works". And check the latest Scientific American cover story to see how this type of technology is the "next big thing" for a wide range of problems.

I bought one of these years ago, and was surprised how well it works. I suffer horribly with mossie bites, big red lumps that itch for days. Such a relief to find something that takes away the itch, that is small and convenient to carry around.

When it wore out I bought another one.
Not too expensive, small, does what it claims.

I'm always the person to get all of the mozzie bites at the BBQ - and I don't get just regular sized itchy bites, but they swell up to the size of a 50 cent coin. It's terrible. But I LOVE the clicker, it is the only thing that works for me. I need to click the bite about 20 times but the swelling goes down, stops itching and disappears a lot sooner than it would otherwise. I highly recommend it.
It actually works! The itching and swelling goes away within a few minutes
It is expensive at first but lasts for a long time, so it's worth it for me.

I wasted my money on this. It does nothing to remove itch or swelling. I feel like a sucker for paying over $20 for it. I received two mosquito bites which immediately became itchy. I applied the recommended amount of clicks which did nothing, so I kept on clicking but there was no change in the itchyness or swelling of my bites.
Nothing
False claims

Mosquito bites?

As I'm writing this, I am currently sitting on my bed relatively itch free with a bad case of chicken pox. Seriously, if you think it works wonders on bites, try having chicken pox and one of these at hand. Absolutely amazing. It's only been a day and I probably would have gone mad without this.
Not just for mozzie bites
Can't find it at the shops anymore -.-

Great for people who are allergic to mosquito bites. Also great for ant bites too and removes the sting. Excellent for kids and adults alike. Have one in the car glove box, the gardening bucket, on the key ring, in the medicine chest and in the camping gear! It's a winner
non chemical, reliable, kids like it
key ring attachment breaks too easily

Was sceptical at first but the way it works (spark diffuses inflammatory reaction i think) made logical enough sense to me to try. It really does help & prevents those sleepless nights scratching away.
I tend to click 6 or more times on a mozzy bite to get relief for several hours
Effective, inexpensive, chemical free
Difficult to click in awkward to reach areas & wish it was more readily avaiable at supermarkets or chemists

I like using natural products, the only thing I have ever found before this product to relieve mosquito bites is Soove, which contains chemicals so I am happy this has come out. Although it might not take the itch away completely it definitely does work to some extent, and I think it works better than putting a cross over the bite with your fingernail as someone else mentioned. Definitely something to try if you like the idea of a natural remedy.
Really works! Doesn't contain anything unnatural or toxic. Inexpensive and the small device doesn't take up much room in the medicine cabinet.
It doesn't work as a magic cure, it only helps relieve the itch.

the mosquito click is something i saw on an add, and agree with the comments about doing the same with your fingernail. this is a little more effective, and is pretty cheap way to do it. it is convenient and can be taken almost anywhere. great for when you have a really itchy and annoying bite. would recommend to those who can't stand mosquitoes or have a bad reaction to their bites.
convenient, small, takes the itch away, affordable enough for everyone
same as what others have said, you can do a similar thing by making and indentation with your fingernail.
