I used them during the bad weather in Ellinida, within Attica and a little bit in Parnitha after the storm passed. They were very easy to put on, on a slippery road where the car wouldn't start. They were very good, I didn't have any problems anywhere, even on uphill points in Zografou and Lykavittos where you can't go without chains. The studs they have got damaged after using them once or twice, as my car wouldn't stop on a downhill slope and it dragged the stud on the road. I had difficulty taking them off because the strap that holds them stretched a lot. I bought them for off-road use in case I get stuck in mud or sand as I go on many trips. I always keep them in the trunk, they don't take up any space, and that's the main reason I chose them, to be suitable for mud and snow. I don't know how they will handle heavy use or deep snow, but even if they break, I will buy the same ones again. They are ideal for dirt because if you loosen the straps, they can function as shovels and help you get unstuck. I would like to have 6 on each wheel if the terrain is very difficult.
