Addalock The Original Portable Door Lock for Travel & Home Security, Durable 1-Piece Door Latch Lock for Houses, Apartments, Hotels, Motels, Dorms & AirBnBs - Lock the Door & Stay at Home or Away

This review is comparing two high end travel locking solutions, the Addalock and the Travelers Security Lock Llc..I really liked both locks, but for different reasons. Which one you choose to take with you will be dependent on your individual needs.The Addalock:Weight: 4.28ozPrice: twenty bucks or so.Operation: A flat, thin steel bar is provided, it looks a lot like a cheap bottle opener. Quality is solid. at one end, there are a couple steel prongs that stick out. Insert the steel prongs into the bolt hole in the door frame, then close the door with the metal wedged between the door and the frame. A red plastic/metal triangular wedge clips to the end of the bar and settles down against the door. Trying to open the door pushes against the plastic which is attached to the bar that is inserted into the frame - not going to open!Pros:LIGHTWEIGHT. This is the strongest selling feature of this device. It is relatively thin, takes up a small footprint, and only weighs 4.28oz. When it works, it works well enough and prevents entry. Ideal for a backpack traveler who has to make every ounce count. Thin metal bar makes it easy to fit into tight door frames.Cons:1) Doesn't fit SUPER snug into the door. It will keep the door from opening or even moving much at all, security is good.... but it's obvious from the other side you have something small and "rattle'y" jimmied into the lock.2) Needs the frame to be at least a fair to middling fit with the door. If it was a REALLLY loose door, I think the lock would fit too loosely and be able to be circumvented fair easily.3) As others have noted, it's not compatible with quite a large number of hotel room doors. Might work, might not.4) A very "standard" door lock will still be able to slide the bolt through a hole in the bar and close normally. Someone from the outside will just find a normal closed and locked door, unless they try with a key. (that part is ok). BUT for anything other than a super standard lock bolt size, it won't fit through the hole, which means it's just the addalock keeping the door closed now... and since it doesn't fit in 100% snug, it becomes obvious to someone from the outside that the main door lock is not engaged.The Travelers Security Lock Llc.:Weight: 9.28ozPrice: fourty bucks or so.Operation: A relatively thick machined aluminum bar is provided. At the end of this bar is a large raised portion. Much like the Addalock, this raised section is inserted into the door and then the door is closed with teh aluminum bar in the jam between the door and frame. A second piece consisting of a notched block of aluminum and two long, padded bolts is then attached into the notch on the bar. The bolts are tightened until they press against the frame and door. Much like the addalock, any attempt to open the door presses against the bolt attached to the aluminum bar in the lock hole.PROS:1) Heavy gauge machined aluminum block. This thing feels solid, and fits together like a precision part.2) TIGHT LOCKUP! Once you turn those bolts hand tight against the door frame, NOTHING is going to move. Someone trying to pen the door from the other side might be led to believe that you had boarded up the door and nailed it down. This thing locks up the door so tight, there's not even a hint of a jiggle.3) Very adjustable. The two independently adjusting bolts allow it to fit any sized door or frame with ease and the above mentioned tightness.4) The bar on this unit does not have a hole in it. No matter what size door bolt you have, The door will not be able to latch with the bar in place. Which means the door will never be "latched" while you have the travelers lock in use. This PRO about this design is that there's a lot more metal in the latch hole, and it makes the bar very structurally sound. And it turns out to not be a Con in my book because the Travelers Lock is so adjustable that it locks up the door SOLID, so nobody that is trying to pull on your doorknob would even realize that the door was "open", if anything it would feel like the door was boarded up on the other side!CONS:1) It's heavy! If' you're a backpacker, this guy is a serious weight investment.2) The aluminum bar is a little thick. Maybe it is by necessity for structural integrity... but it's thick, and will have trouble fitting into tight tolerance door frames.BOTTOM LINE: they still haven't made the perfect lock yet. If they could make a Traveler's Lock with a thinner steel bar, that would be nearly "perfect". The traveler's lock will work in the loosest doors, and lock em up TIGHT, but may have trouble fitting in very tight door frames. The Addalock won't work with the loosest door frames, and locks the door a little looser, but it will work in very tight door frames.If your primary concern is:Weight - get the addalockSecurity - get the travelers lockflexibility/maximum coverage - get both

Very easy and secured the door correctly.

Great as described very sturdy.awesome for hotels.would even give as a gift.

Only problem I have with it is it doesn't fit all doors, but when it does fit it works perfectly.

It is great. Thank you

Very good invention... No "installation" necessary in terms of screws etc. Slips in between just fine, super simple. For the occaisional tighter fit, just turn the knob first, and then close it in... Simple. Have'nt tried this in a hotel yet... I believe it will work in most Motels though. Had a RIDICULOUS "landlord" and workman that would just go into people's apartments whenever they flippin' wanted! Almost killed a guy during one of these events. Bought cameras, and rigged all kinds of barricades to keep these nuts out and myself out of jail because of them. Wish I had just ONE of these during that truly miserable time. Now, no matter where I go, I have a few of these no matter what. I'm a very large man with serious combat training, and I would much rather let these babies do a terrific job as opposed to having to resort to setting up booby traps ever again, or ending up in court for mangling some fool for foolishly intruding.Though not really useful for when you are OUTSIDE, it is funny to set it up backwards just to show there's something at instant one they probably don't want to mess with when it comes to you insisting on your privacy.As stated in the beginning, I wish I had just one of these awhile back, but I have learned alot from such ridiculous circumstances, and have since learned much more civilized methods to guarantee my privacy which to me is priceless. This little rig does help quite a bit... you will like it. It is also adjustable and again just pretty neat, though you would be wise to pick up a few other security tools and enjoy peace of mind without possibly harming some stupid intruder, deserved or otherwise.UPDATE:Picked up yet another, and it is designed very differently. It is difficult to explain how, given the very unique/clever design... Best way I can describe it is that it's depth adjustability is dramatically different, the ones prior being much more versatile. Still great to have, and you can be sure they do the job right. I'm glad I have some of the adjustable ones... different doorways simply do not fit the most recent design. I'd write in beforehand asking if these are the 4 notch adjustables (ideal) or the less versatile tringular notch design, Sidenote- I found a GREAT place... everything is clean especially the water (thank god) but sure enough, a workman who was not aware I happened to be home that day (I male sure *everytime* now always being certain of when they decide to drift by) tried to come in without prior notice/permission... but this did the trick beautifully. He tried for nearly two minutes (as hidden video also shows) trying the right keys first, then thinking he must be using the wrong ones, trying others, and then trying the correct ones again, turning the knob and pushing with no luck at all. I fought myself from confronting him on the spot, as I am really trying to not let this kind of thing make me as upset as it once did (albeit for appropriate reason) and instead decided not to, opting to see if he was going to mention anything about it. Not a peep... as I expected. Did ask me later alot about my expensive electronics and reminded him I'm pretty good with stocks, have all my financials to prove it and offered him a discounted rate for some investment consultation. Shut him up entirely after that. In any event- It just goes to show you.., if someone else has keys to your place, nosy utterly wacko girlfriend (the i intial reason I became interested in things like these) workmen, landlords, don't be shocked... happens every day and almost certainly to everybody- save your peace of mind and right to prevent nosy weirdos from bothering you. Get some good locks... they exist for very good reason, and there are few if any good reasons not to use them.

Works great for standard home door locks, but does not work with most hotel room doors where the lock has multiple prongs. I have tried it at multiple hotels and have not been able to use it once.

The extra lock is easy to carry in my purse for trips. It is very easy to quickly install on hotel doors.
