Thank you all.
I'm not worried about it not having PC connection as long as you can download the data to the PC.
I emailed the company selling it and they say the internal has space for storing the weather data of 35 years!! (considering it records every 30 minutes)
Mcrossley, I thought it had a pressure sensor, at least it shows: Barometric absolutely inHg.
I had almost decided to buy this one from the same vendor as it's the new version of Fine Offset at good price:

But I thought maybe this "Poor man's Davis Vue" could have better quality sensors or more accuracy and be worth extra €100 over the Fine Offset, but as it seems it's not a popular model I guess it's hard to find out.
