VERY hot, briefly quite painful if you are sensitive
Reviewed in the United Kingdom on 13 September 2021
This product was quite simple to use, but I would warn anyone sensitive to heat or with sensitive skin, that it can be quite painful, not just "uncomfortable" as stated in the accompanying leaflet.
I'm more prone to insect bites and moderate to quite bad reactions, compared to most people I know (for example, I can get more than 10 or 20 bites which swell up quite badly, when companions may get one or two small bites or none at all!)
I used this in combination with an antihistamine cream, and for some bites it was very effective. The pain, itchiness and swelling from the bites was significantly reduced and the time to heal was faster (than with no treatment or antihistamine cream alone).
However, for bites on my ankles, most likely from fleas from a stray cat we were looking after, there was only minor improvement.
Overall, I would say this is a somewhat helpful device, although for the price and pain and discomfort and lack of effectiveness in some cases, I'm not sure I would have bought it if I had been able to try it first.
Due to my sensitivity, as advised by the manufacturer, I only used the 3 second setting, which was all I could tolerate. It may be much more effective with repeated treatments of 6 seconds, but I wasn't able to test this.
As it helped for some bites, and it may help other family members more than it helped me, I will keep it and continue to use it, if I can't avoid getting bitten!
