@AleArg i bought it several days ago and just used it today for the first time.

I installed the drivers from tp-link website.

I tested it in open air ( under shade not exposed to direct sunlight of course ) .

The temperature was around 24-25 degrees celsius and a bit windy.

The adapter ran ok all tough i experienced a few disconnects at first but soon all was ok.

I used it to connect to my house on the second floor in the garden .

I connected trough parsec to stream some games from my pc.

I didn't find any lags or drops in quality of the stream that would indicate any drop in performance.

My unit did got pretty hot.

I could hold my fingers on it but it was at the point where it started to burn a bit but more but nothing too serious that i needed to move the fingers.

I also want to know if this is normal behavior from this device or not.

As we all know heat is one of the major problems with electronics and should be kept in check.

Can some tp-link representative answer this question to us ?

Thank you !

A small update.

After speaking to a tp-link representative, he told me that the normal working temperature should be around 40 degrees celsius.

I went to the store from where i bought it and exchanged to an identical model.

This one doesn't get nearly as hot as the previous one .

In conclusion this is not normal and if you plan to use it long term you should try to change it.

Take care !

@Xsander  thanks for the information. Not sure exactly, but I think is more than 40 celsius degrees in my case in concordance with your comments about it is not possible to maintain my fingers more than 10 or 20 seconds in over the device.

Thanks again!

 i have the same issue, i bought this adapter a days ago, and i saw the temperature is over a 40c. I'm in touch with tp-link support on brazil and they don't know nothing about that it's normal or not. Anyone have any solution for this?

@AleArg

I am still using the device and I think is working at 45-50 °C; I can matain my fingers at the center of the device by 20-30 or more seconds but it feels really hot. I did not change it but if you can do it, go ahead (based on previous comments). My plan is to keep it but I am not going to buy again any hardware from TP-Link again.
