Do OnGuard MinPin Locking Skewers provide adequate security?

I read one review (http://www.rei.com/product/842891/onguard-minpin-keyless-3-piece-locking-skewer-set) saying that the skewers can easily be defeated. Another review (http://www.amazon.com/review/R3CTA0K40XLP1K/ref=cm_cr_pr_perm?ie=UTF8&ASIN=B0077T7CR6&linkCode=&nodeID=&tag=) said the skewers could probably be either broken or defeated w/ a magnet or pliers.

For anyone who has used these skewers, how would you describe the security that they provide?

I haven't used them myself, but I've been asked to remove a broken set. A customer came back to their bike and discovered that a thief had tried to force them and failed. But not before breaking both front and rear lever mechanisms. I got both off without damaging the rest of the bike at all, with a cutting disk in the grinder they come off in seconds. Anyone can buy a battery grinder for $99 and youtube has a collection of "bike thief being ignored" videos so I'd rate these as "casual thief" resistant.

Also, the "locked" mode is exactly like the "stuck" mode of a normal set of QR skewers. Unless someone knows that they're the special locking ones they'll just apply more and more force until something breaks. So every time you take it into the bike shop or put it on a vehicle you will need to attach a note to the bike to that effect. I hope they come with stickers or something.

Given that you're looking at spending money at all, I suggest something more effective. A set of Pitlocks cost about $105 from Peter White (US) or 95 euro from pitlock.de. And they're made from hard stainless steel so a cheap battery grinder will take a long time to grind one off.

used these for a couple months on my mountain bike. These are just a pain. They are hard to re-open, even when you are doing it right, especially on disc brake bikes. I also find the seatpost QR clamp ridiculous, who wants to flip their bike over to move the seat up / down (I'd rather stick with a bolt on seatpost). –  Benzo Jun 25 '13 at 12:51
    
@Benzo What is a pain? The OnGuard MinPin Locking Skewers that I referenced or the Pitlocks that Moz mentioned? –  Chris Morris Jun 25 '13 at 20:56
    
With the PitLocks I have a keyring about 50mm in diameter with the pit on it, and that's enough to both lock and unlock. The hole is 5mm so you can put an allen key through it, or use a 15mm spanner. The latter will let you get them ridiculously tight (if you have a fixie and no chain tug, for example). –  Mσᶎ Jun 26 '13 at 2:39
    
OnGuard MinPin skewers were what I was referencing. I think the Pitlocks, while expensive, are the best skewer-based security you're going to find. –  Benzo Jun 26 '13 at 11:47
