In my opinion, botch

I tested the unit after receiving twice.
The first time immediately with my existing since 2 days mosquito bites. I have around 20-30 times clicked on it (as to instructions are just 4-10 needed). Much to my disappointment it also then still itched, even more briefly, because of the surge comes a scrape equal. The swelling is of course not gone away.

Good, I thought, standing on the guidance, after all, that you should apply it immediately after the bite, maybe I have to say the product wronged.
The day before yesterday I had therefore the ideal testing opportunity: I was repeatedly stabbed in the beer garden and not even 30 minutes later, I do not even felt an itch, I applied the device to all stitches generously. The result was the morning after:
I still had swelling and the stitches have itched badly. Even after repeated application, did absolutely nothing.

Two stars I give only because I normally very badly react to mosquito bites and this time was not quite as big. But that is probably more likely, therefore, that this time I have forced me to not to scratch, because I did not want to tamper with possibly the effect of the T177.

*** Update (3 stars) ***: Even before I was about to send him back, I have the Eco-Click applied to again 2 new mosquito bites who had just emerged and it has worked well this time. The difference in these engravings was that they immediately began to itch already and there was a great redness immediately. In the cases described above, it has indeed been itching after several hours and is swollen.
I suspect, therefore, that there are different types of mosquitoes (mosquito bites?) And therefore this product only works with some.

Conclusion: If the stitches where it comes directly after the bite to itch and redness of the Eco-click helps me already, at least it reduces itching and swelling significantly. But with those where you realize the consequences of only a few hours after the bite, because it helps me anything when I do a "click" immediately after the bite and in addition. It is then still the swelling and itching.
(Perhaps it is indeed to puncture depth or size of the mosquitoes ....)
