ABUS180IB/50 All Weather Solid Brass 4-Dial Resettable Combination Padlock with 2" Stainless Steel Shackle

Use several of these in our youth baseball league, all in outdoor environments not at all protected from the rain. Never had a problem with these. A bit pricier than others but it's the only one so far that's been reliable. Master makes a big, fancy looking lock that's supposed to be for outdoor use. We tried a 6-pack of those and every one failed. The dials just freeze up on them, you need to bang on the with something or sometimes just cut the lock off entirely. Go with these if you want an outdoor lock.

Still operating reliably after 15 months of all-weather outdoor use. We had a couple of other brands of locks fail to open after a month or two. Our Abus lock is used by multiple people who are guests at our rental property so we need something that opens easily, regardless of weather.

I didn't want to spend nearly $30 on a lock for this outdoor application, but this model appears to be the only thing on the market that fits the bill, and I'm grateful for it.I needed a combo lock for ease of use, especially to share access with others.The application is outdoors in rainy humid Florida. I didn't want to risk a combo lock rusting and seizing up over time, if I were out of town and someone needed access to feed pets. The other combo locks about this size on the market deemed about half the price and half the quality of this one.This a bus lock operates smoothly. I agree with other reviewers that the number dials spin much more easily in one direction than the other, but it works for me so I can live with it.With a single hand, I can lift the lock on it's chain, hold it upside down and enter the code with my thumb, then squeeze the lock closed in my grip so it pops open. This is so handy because I often have the other hand full when I want to get access.

Terrible, terrible product. For work I am constantly on the road, and my tools are in a Pelican case which typically rides in the bed of a truck through all kinds of weather. I was looking for a long lasting lock that would hold up to the elements and protect my investment. This was one of the few "marine" locks that I could find with a long enough shackle for my Pelican case. Once the lock came in the mail I set my combination as per the instructions on the packaging. Once I set the combo and went to reopen the lock, nothing happened. Sure enough my combination was not working. I tried the default combination and still nothing. After calling ABUS and leaving a message I turned to searching videos online to find a way to open the lock. I found that the lock was actually pretty easy to open with zero locksmith skills. I simply followed the advice of one of the videos I came across, which was rapidly spinning the combination dials while pulling up on the shackle. After about 10 minutes of doing this while sitting on the couch, the lock sprung open! Although happy to have the lock open, I was disappointed that a $25.00 lock was so easy to manipulate.So now with the lock open, I was able to determine the combination (which was about 8 numbers off from what I had thought I set) that the lock had be set to. I used the included key to once again set my combination. This time I checked the numbers at least 10 times prior to setting it, thinking that maybe somehow the dials shifted during my initial combination input. Success! My combination worked perfectly. I locked and unlocked the lock at least 20 times just to be sure. I put the lock on my tool case and called in a night. This is where it gets good.....The next morning I loaded up my tool box and headed to work. It's important to note my job often takes me to remote locations, where myself and my team work entirely out of my toolbox... Once onsite I go to open the lock, and nothing happens. I check my combination and sure enough, nothing happens. My anger at this point is through the roof, and unfortunately my lock manipulation trick is much more difficult when the unit is installed and I'm standing in the blazing sun. Thank goodness I had a 20V grinder with cutoff wheel on hand, which made quick work of the lock.DO NOT BUY THIS PRODUCT. If you don't need the longer shackle than go with the Seasmee marine lock, I have it on other items that stay outdoors and have not had a single issue.

Some features that might be considered annoying:When rotating the dial to the correct combination, the lock does not open if you then pull on its shackle (like most locks do) nor does it open itself. The shackle remains closed. You must push the shackle in and it then springs open. This can be confusing to someone who you may give the combination to but is not familiar with requiring the shackle to be pushed in. That person may believe they have entered the correct combination but can’t get it to open.To close the lock shackle and relock it, the combination must first be changed from its value used to open it, otherwise the shackle just springs back open. This is probable a good thing as you could not accidentally reclose it and have it actually be unlocked if you were able to reclose it and forgot to spin the numbers to relock it.The combination dial digits cannot be rotated beyond 0 to get directly to 9. You must rotate 0,1,2…9. Thus if a digit in your combination is say 2, when changing the digit to close the lock, you cannot spin the dial down from 2 if you wish to leave the digit at say 8. This is probable a feature meant for being able to unlock when you have a hard time seeing the digits. You could spin them until they cannot spin anymore, meaning they are then at 0. Then you simply move them one digit at a time, counting how many clicks you move until you get to that digit’s value.It requires a special key to be inserted into its side in order to change its combination. I can imagine that key getting misplaced after a while should you wish to change the combination in the future.It has a stainless steel shackle with brass body, so seems good for outdoor use.The Master Lock 1175LHSS also has a stainless steel shackle, does not require a separate key to change its combination and I believe will open by pulling on it after the combination has been entered. But it might be able to be reclosed with its combination still set to its open position, requiring its digits to be remembered to be spun.

Been using these for years and they just work.
