The Flow Security Systems Faucet Lock II | Magnetic Key | Prevents Water Theft, Secures Outdoor Taps, Promotes Water Conservation | Fits Most Outdoor Hose Bibbs | FSS 500 | Keyed Randomly | 1 Pack

So, I might not know JUST HOW GREAT these things are if I hadn't spoken to the owner of the company today, who phoned me personally at home on a Saturday after receiving a distraught complaint message that my two locks were defective. I had looked up the company through my Amazon order and sent the message, after which I saw that they have a customer service number I could call M-F.The company owner called directly from his personal cell and talked me through a little work-around that got them working again.So, how do they work and not work? Magnets! Once these fit onto the hose bibb (with your key inside) you hear and feel a sort of click into place. Then you remove your key (containing a magnet), and your precious water is on serious lockdown from thieves. Once you need to access your water, you simply insert the key and start unscrewing.My hiccup today was that the lock kept turning in place rather than unscrewing, which is exactly what it does for the people you want to keep out, and what you want it to do to them. But when your magic key is in there, you want it to come off. Apparently a couple of taps on the locking device itself helps tap the "sleeping" magnet back into place, because it worked on both locks that were jammed up. The gracious owner still offered to let me return these in exchange for the brass version with a traditional key at no extra charge. He explained that the brass ones are more costly to make, which is why they are more, and that w/o regular maintenance like WD40 they could fail from corrosion. But that the magnets should last with no maintenance at all, which is how they came to be invented. And they're cheaper to make because the parts are less than brass. Fascinating!Even with the hiccup today I opted to take the leap of faith on the magnets, because I just love the innovative technology.I think if you've checked the listing you can see you can order as many as you want all keyed the same (one key = multiple locks) or keyed differently, but that is a nice bonus for those of us who like it simple. The keys are lightweight and plastic and just plain bizarre. The locks themselves are very heavy and feel sturdy and well made.It seems that the occasional one might fail or be a lemon, but rarely, and if so, it sure seems this company will more than take care of you. I've never gotten service like that EVER. It's rumored the world was like this back in the '50s, but I'm an unfortunate product of mega-corps and phone tree robots that never get a human on the line. I was really blown away by this level of service.

I bought this Water Lock three years ago in 2020. It protected the outdoor faucet at my condo from others that were turning the water and leaving it running. Easy to install / uninstall. Last week, the lock would no longer stay locked. I reached out to the company and Mark, president of the company, responded to my email and is sending me a new lock. That is great customer service!This is a great product to keep others from wasting water and charging you for their bad behavior.

I installed 8 of these on rental units. Easy to install. Tested it and it locked and unlocked as expected. Seemed like a good solution. Problem is after about 6 months they no longer unlock... put the key in and the head just spins and spins. I tried multiple of the right number keys and none worked. I used a small screwdriver to pop off the lock ring and removed the lock. I could see dirt/grime/mildew around the magnet in the lock, preventing it from moving, and of course unlocking. Obviously there is not a sufficient seal to prevent the elements from contaminating the innards of the lock, which over time rends it useless. Buy only if you never want to remove because after awhile you won't be able to remove it except by destroying it.

Works great. One key fits all my faucet locks!

Great product that works exactly as it should. Almost too well. If you lose the key that comes with the lock, you are out of luck with accessing that water source again.

my lock failed after 3.5 years but when I reached out the the company they called me immediately and walked me through removal of the broken lock. It’s now garbage but they even offered me a discount on a new lock. I ordered again through Amazon because I was so happy with their service I didn’t want to take a discount. Thank you again!

*******Update August 2024*******One of the two locks has now stopped working just as they both did the first time. Reducing to 3 stars because although the devices themselves don't appear to last as long as might be expected, they are a good concept, compact and the company is responsive when contacted. I think I will just leave the stuck one on till I have no choice but to remove it using the tool provided by the vendor, but once removed I will look for another solution to securing the outdoor faucets.****** Update September 27th, 2023 ******I found an email for the company and sent a message with the issue I was having. Within a couple of days I didn't so much get an email response as a personal phone call from a company rep. He asked me a few questions about the devices and said that the issue might be due to my having an older version of the product. He asked me whether I wanted a refund or a replacement. This is fantastic customer service as there are always those who want a refund. For me though, I LOVE this product when it works so I said I would prefer a replacement. I also asked about removing the existing non-working devices. Not only did he send me the newer version of the product as promised, but also provided a tool to remove the old devices free of charge. When everything arrived it was pretty easy to remove the old locks. I replaced them with the newer versions and for the moment they are still working. I will wait a few weeks as happened with the first ones I bought and make sure these still work after that time. But for the moment, I will raise my rating from 2 to 4 stars if only because the devices are great when they do work properly and most especially for the stellar customer service from the company once they knew I had an issue******************************************************************************Well if this would work properly I would love it. It does exactly what it's supposed to do. Lock your water tap away from thieves. It worked well the first month or so, but just yesterday (about 6 weeks after purchase) I tried to unlock it and it just turns as if there was no key inserted. I bought two locks keyed the same and I've tried all four keys. None of them work *on either of the two locks*. Kind of like they both broke at the exact same time. This can't be coincidence. Maybe these were in a bad batch or something but now I'm stuck not being able to use my outdoor taps. I tried to find a contact for the seller but can't see any contact info on their store page or on Amazon. Anyone have an idea how I can remove these without damaging the water tap itself? Shame because I really like these.
