Stainless Steel U Lock, Outdoor Weatherproof Lock with Keys, 4 in.Wide, Adjustabl Shackle Marine Padlock for Boats, Gates, Bikes, e-Bikes, Scooters, etc.

This is a massive, very well-made padlock and keys. Just its appearance will be enough for a thief to pass it by and look for an easier target. Its all stainless steel construction is a bonus. I am extremely pleased with this purchase.

I wanted extra security for my double front door and my French doors and the Sedorti U Locks are perfect. They fit nicely over the handles and are very secure.

This is an excellent, long, "U" shaped lock I got for our gate in the backyard!It's extremely well made, of "highly" strong, durable stainless steel and construction. Since it has a very long, "U," it's quite versatile in what you are able to lock up with it, like: your fence gate, your garage door, your utility door, a bike, a BBQ Pit, an expensive lawnmower, a "trailer," all sorts of valuables and equipment!Unfortunately, most of us do not have adequate storage space in our backyards, or even adjacent to our homes, via a "storage room," or a portable, outdoor storage building of some sort, and so on. With a lock of this type, it does help eliminate or at least "reduce" your fears about potential theft concerning your assets, within your property or even inside your home or garage facility.Only slightly negative remark is that this lock is VERY pricey! Maybe a little too much, I'd say half it's retail price would be more fair.Excellent, Quality "U" Lock.5Stars!*****

This lock has been tested by the Lock Picking Lawyer. The device is very easily shimmed with the leftovers of an aluminum can. Picking took a bit over a a minute. :(

Such a cool lock.Weights just over 3Lbs.The keys are very nice and work either way.Definitely will use with my boat.Nice product.

This U Lock is a vision of modernity, boasting a full stainless steel design and laser-cut precision. It's substantial, weighing 3 1/4 pounds, which adds a sense of robustness but also results in a rattle. The key operation can be tricky due to the lock's narrow U shape, i.e. my wrist gets stuck fiddling with the key. Its stainless steel build resists rust, functions underwater, and performs across varying temperatures, but it also rattles, so you might hear it when carrying it.

Works great, is easy to use, has solid-made construction, heavyweight, am very pleased with this item.
