PACLOCK's 90A-PRO Padlock, 1/4" Diameter Hard. Stainless Steel Shackle, 1-3/16" Tall, High Performance 7-Pin Cylinder w/ 1 Key, Keyed Differently, Blue

I bought this lock mainly to complete Paclock’s “200k challenge”, where you record yourself picking and gutting the lock and they reward you with a patch and certificate. It arrived today and I’ve since picked it open 3 times. It gives excellent feedback and is super fun to pick. Its actual difficulty level is debatable though. 7 pins and 200k key combinations is useful against certain attacks but a good picker will get it right open, and without getting into minutiae I’ll say there’s a very certain method to getting it open quick, and now I’m halfway tempted to buy another one and test that theory. I wonder how much of Paclock’s sales on this come from people like me anyway. My goal is to keep my picking and gutting video under 5 minutes and that won’t be too difficult. I prepared myself for this with a tricky American Lock 1100 and a German Abus 72/40 and I was well prepared. Now onto real life applications, this is a super heavy duty lock and the 7 pin keyway cannot be picked by anyone without some pretty significant skill and experience with security pins. The weak point on any padlock like this is the shackle and the best part about this is that the shackle is replaceable. Small consolation if it gets cut off and your stuff gets stolen, but at least you probably won’t lose the lock. Finally, these come with stainless steel pins and if you get one with a stainless shackle it just will not rust. And finally it’s a quality American made product and operating it is just satisfying, whether you’re turning it with a key or a tension bar. Guess it’s time to get recording! Got a patch and a blue belt waiting for me.

It's an industry standard for a reason, tight tolerances, seven Pyne total six of which are security pins (alternating spool and serrated and standard in the seventh slot), no spring resistance on the core: picking one open, you have to know what you're doing and be hone in your skills. I'd put it ahead of dozens of locks costing two or three times as much by other companies. Place it comes in a whole bunch of really cool colors so that's super cute and fun. Whether it's customized for your personality or color-coded locking systems, you can go nuts get a whole rainbow of the paclock pro 90 a's.

Well, I bought this for locksport practice and have yet to give it a try. I'm quite sure it would be sufficient to safeguard your goods.

As an avid practicing locksport enthusiast at the intermediate level I find the Paclock 90a Pro to be a formidable challenge. With it's 200k possible distinct key patterns and often challenging bitting these locks have provided me with a challenging puzzle to solve. Paclock 90a Pro locks are an industry standard known for their quality and reliably. Worth every penny.

Anyone who has watched the Lock Picking Lawyer on YouTube knows that Paclock makes good products, and that they're engaged with and responsive to their customers. Because of that, I bought several of these in the standard size. When I wanted to get some of this model of lock (90A-Pro, keyed alike) with a longer shackle (2"), I called them. They told me to place the order on Amazon, then give them the order number, so that they could adjust it in their system. I did. Unfortunately, the locks that were delivered had the standard shackle length. I called back to their customer service line and (as before) very quickly got a live, pleasant, helpful person, who apologized for the error, and gave me two options: Paclock could provide a longer shackle and I could install it, or they could mail me two new locks with the appropriate length shackle. I have some ability with a screwdriver, but I'm not confident taking locks apart, and don't have the tiny screwdrivers needed for the set screws. I asked them if they would mind making the shackle length an extra 1/2" longer, which they graciously agreed to do. A few days later, I had my 2 new (and longer!) keyed-alike 90A-Pro locks. They're perfect! I know a lot of companies get bad reviews because people are more likely to complain than praise on a public forum, and unfortunately that leads to the impression that nobody has quality products or service anymore. Paclock excels at both quality and service. If you want great locks and great service, buy from Paclock.

Well made, easy to disassemble. Not an easy lock to pick or rake quickly. Terrible feedback and crunchy pin movement. Core has a little bit of play within the padlock, which adds to the sloppy feel. I can open mine easily in under a minute, but that’s only because I’ve been practicing on this lock for a couple weeks and have memorized the binding order. I would use this as a gym locker lock and feel pretty confident about it. Ultimately if someone wants in, they’ll just cut it, but if someone relatively unskilled were raking and bypassing locks quietly, they’d probably end up skipping this one with how long it would take them to defeat it. I both love and hate this padlock, and will probably buy more Paclock products in the future. Good stuff.

Look is very well built and finished, very secure 7 pin core. Family-owned business and made in USA. Highly recommended, don't waste your time with MasterLocks, buy this instead.
