Sesamee K5003/4 4 Dial Bottom Resettable Combination Padlock with 1-Inch Hardened Steel Shackle and 10,000 Potential Combinations

i specifically wanted this powdercoated zinc lock because brass used in most locks contains lead that rubs on your fingers. this lock i believe uses brass on the inside, but that's fine with me. the exterior of this lock doesn't seem to have any lead in it. this lock is a bit heavy for the level of security it provides but that's fine with me too. there is a better lock from Sesamee which is a Chrome Plated Marine version of this lock ... but i already have that one and i wanted to have two locks in different color so i know which locker has what in it. So i have a Chrome lock and a Black lock and i rate both 5 stars.if you only need one lock and don't mind the slightly higher price the Chrome is the one to get because it is stronger ( Zinc is not the strongest metal ). but i still rate this lock 5 stars because it is EXACTLY what i wanted, namely a lock without lead on the surface that was different from my Chrome lock. the operation of both locks is identical.finally if you don't mind a brass body lock get the marine lock from ABUS - i have returned mine because i realized it contains lead, but the ABUS is very sexy, it is designed in Germany, it is Marine grade and the mechanism clicks perfectly.that said neither of these 3 locks provide a high level of security. i'm using these for my gym and pool lockers. if you need a lock to secure something like a motorcycle etc you will want something more secure than this.

Had one of these for "years" and it was a great lock, but like all things it had its day. I searched for one just like it and here it is. I highly recommend this lock. CANCEL MY RECOMMENDATION, I WOULD NOT NOW RECOMMEND THIS LOCK!!!!!Had this lock now for a year and one day it decided that it no longer cared to open and I had to get it CUT OFF! Multiple attempts with the combination failed to open it. It worked fine up until that day. NO WAY would I buy one of these today, the quality just doesn't seem to be there like it used to.

I purchased two of these for a motorcycle cargo trailer. They are subject to moderate to high vibration. Before I used them on the road, I changed the combination and verified that it changed and I could open the locks. I then, by hand, "rattled" the lock. One of them opens everytime with 5 to 10 good yanks. I have never seen this on a Master lock.

Rated 'average' because I don't know what I got. I bought this to be used out of doors to secure a gate.The "Technical Details" include:"All brass internal mechanisms for strength and durability"Which would be good to stop it from rusting up.But the product packaging says(see image above):Body MaterialX ZINC diecastI have it out on the fence and it will probably take 2 years of weather to see if it locks up (no pun intended) due to oxidation. I would think that brass internals would be something touted in the products packaging.

I was looking for an affordable 4 number combination lock for some cargo trailers. They can be hard to find. These locks cost much less than the ones I had before, which are no longer being made. I dipped them in plasi-dip to protect the finish on the trailers and to color code each trailer. I was very happy with these locks, but after use on dusty roads they started to get stuck and woudn't open. This had happened with the other locks I had before - but with these Sesamee locks I found that a sharp rap on the flat side will open them (as long as the combo is set correctly), so I think they will still work for me. Sometimes I used just my hand, sometimes it takes a hammer or a rock. I know it doesn't sound great, but I think fine road dust from gravel roads will jam most locks. At least these will still open when you tap on them. I wish someone would make a cover to keep the dust out.

Absolutely solid, tough, and easy to use. You'd need a serious bolt cutter to get through this one.

Great lock for the gym. Only wish the numbers were a little brighter.

Absolute garbage, less than two months usage, on standard door lock outside, and now rust all over, and I barely got it open... In fact when I test it again now, you have to try about 7 times before getting it open after locking... Obviously going into trash before it locks up totally, let alone the rust is unforgivable.Is it this hard to make an outdoor lock?
