Opinions required: Trans X security skewers

worked on mine, I lost the lever and was so surprised at how easy it was I binned them

^ I agree,
for a cheap pair of wheels you don't really care about they work as a slight deterrent but are easy to open. Some cities like Berlin they are really popular so loads of folks have the 5 sided allen key so it makes them useless. I've personally found you have to spend a fair bit more cash to get some more secure skewers, I've got on with those pitlock ones for a couple of years and the Kryptonite skewers for about 10, out of the 2 I'd recommend the Pitlock ones as they are easier to tighten and undo.

Hmmm...
Maybe I'm just a bit of a numpty with the pliers.

They certainly aren't 100% security, that's why I always still secure with two locks through the wheels and frame.
