Anyone vouch for the quality of these?

Looking at this for a keyless gas cap:

Does anyone here have experience with this model?

Also - I know there's a thread around here about the bolt size needed for mounting these (I'm assuming the length will need to be different with a different gas cap).

Never mind - found the other thread (the huge one)....

Looks like 1 1/8 inches long for the hardware....

Another question though - is the lack of a vacuum port going to be a problem (asking because Silver noted that the more expensive option had one)?
