I have nothing bad to say about Weras warranty. I bought a ratcheting screwdriver from them and it broke after two weeks of use. I sent an email to them and explained the problem i did also included a picture of the screwdriver. After one week, I got a new screwdriver home delivered.
I'm using this set from wera:http://www.amazon.co.uk/dp/B003THFWHW/?tag=atomicindustr-21
I went for interchangeable blades since i don't use them all the time, only when i'm working with current on, otherwise i use weras laser-tip drivers.
