What are your experiences ?

Are they so hardy as it is said .. ?

I don't know what you have heard or read. For me there is no Citrus except Poncirus which is hardy in Zone 7b. All mentioned will die after -10°C

Well, the 10 degree Tangerine has a wrong name then ...

Actually, a citrus tree really does not have an actual low temperature that the tree will be hardy at and still survive. There are so many factors that influence what temperature a citrus tree can experience, and not be damaged or killed. If the previous weather had a warm spell prior to a cold event, citrus completely lose all the cold hardiness that the tree had build up, including Poncirus. The duration of the cold spell also is a factor, the water content of the tree still is another factor affecting how hardy a citrus tree can be. On top of all the above, disease, and insects must also be considered when it comes to "determining" the surviving temperature of a tree at any giving moment in time. There is no one actual low survivable temperature. It all depends.

You mean continuous frost and young plants. For mature hardy citrus temperatue -12C is quite endurable. Last winter in Nikita six mature Yuzu trees lost all the leaves, but now the crown is not damaged and the threes began blossoming. By the way Junos isn't most hardy citrus plant.

According to the weather archieve:

in the February there were two periods of continuous frosts 6 and 7 days long with short break. It is abnormally cold. The minimum temperature was -11,9C. Snow kept more then a month.
