Kurtzy 4 Digit Bicycle Code Lock - 16 cm with Long Handle - Waterproof Bicycle Lock with Reset Code - Electric Scooter, Gates, Mountain Bike, Sport, School, Shed and Lockers

WOW...I have had two of these for a year+ and they have always been sensitive at times, and sometimes they just fall apart, literally, into 6-pieces. But I have always been able to realign the four rings with the red dots and then they are ok for 2- months, 3 months - then bam!THAT IS WHY I KEPT THEM ALTHOUGH THEY ARE NOT REALLY RELIABLEBecause I could fix them when needed and they are the only device I found to fit my needs.Last week one fell apart and I have not been able to realign it.TODAY...see photo...the one on my armoire will not open. I have tried and tried. So...I tried to take off the knob. NOPE The door hinges, NOPE...So I took the back off of my armoire in order to unscrew the knob which had eluded me. NOPEI cannot access the back of the screw from there.ARGHHHHHHHHHHHHHHHHHHHHHHHHIt worked great for a while but had glitches that I could fix...The typical --- It works great product...Until it does not.DO NOT BUY THESE...I know they work for situations that are hard to take care of. I am frustrated, tired, and a little bit angry.A refund would be nice but will not be enough to salve my aggravation and all the time I have spent working on them. OF COURSE...They NEVER refund due to a review as you know and there product apparently usually last beyond the AMAZON return date. SO CONVENIENT... Wouldn't be better to please the customer and sell more and more?

Instructions were very clear and understandable. Programs/adjusts to custom lock digits easily. Perfect for my outdoor barn door window shutter application. Reviews above discuss instructions and difficulty understanding how to use, maybe things have changed over time but not my issue at all. Also review complains about not being secure enough; it's descriptions says what it's used for and works perfectly. Doesn't say use for front gate at Fort Knox. I highly recommend this product. Ordering 7 more for the rest of the windows. It will be very nice having all the same combinations for the hunting lodge windows.

Total junk. The loop is a very small diameter metal....it is not remotely heavy duty as the description says. It could easily be cut with bolt cutters, and quite likely it could be cut with heavy duty wire cutters. It is fine for low security jobs, like a locker in gym, but to trust anything valuable to this is pure foolisness...I dont get the other reviews.....sure, it may lock and unlock, but it is a low security device. Far too easy to cut it. And, as others point out.....no instructions for hkw to set the combo.....are you listening Amazon? This is a true POS that is not described accurately, and the lack of instructions is not acceptable. I am sending it back. Dont waste your money

I am using this lock to keep the doors of my French door fridge locked because I have a teenager who likes to raid the fridge in the middle of the night. For that it works great and is sturdy, I just would probably not use it to lock a bike unless I use it as complement to a main and more sturdy lock, you know, as extra insurance.

Used to lock our shed

Came apart after a few years

Very sturdy. Works well and easy to operate. Used as a cabinet lock.

Had this for six months and it’s been nothing but a pain. If there’s any moisture at all inside, it freezes and is impossible to open. The numbers must each be perfectly aligned (down to the tiniest mm) meaning it takes forever to open. Currently searching for a replacement as I’ve just about had it.

Hängt das ganze Jahr im Freien am Anfang mit Mos2 eingesprüht weil wir neben den Feldern liegen keine Probleme

Lo usamos para un clóset y está muy bien.

Spot on great purchase

Tal y como aparece en las fotos, muy fácil de configurar. El grosor del grillete es suficiente para disuadir. Cumple con mis expectativas.

Déçu. Le u se détache complètement à l'ouverture du cadenas
