I have pitlocks and have had to cut/break them so I can vouch for their durability.
I bought the set which inc. the seatbolt. B/c the seat clamp wasn't flat on both sides and b/c I was retarded, I tightened the bolts too tight, bending the pitlock bolt and then had to saw thru it to remove. It took me ages to cut thru.

On the upside it sold me on the quality.
