Two answers for the price of one.
They look good value for money, but don't know who's used them. Most people use McGard.
The nuts with the locking mech on the outside of the nut are more vulnerable to thieves than the McGard type, but as only another f/tf owner would be able to use your wheels, there is a reduced chance of theft, anyway
Worth a punt at that price?Looking at the ones I posted and several similar they seem to all have the same pattern on the lock nut which suggests to me that they only have 1 pattern and that is why they are so cheap.
