Superb product. Must be precise w key to lock or unlock.
PRO -- Showed this to neighbor, a county sheriff. "Amazing lock." "No one will steal your e-trike!"This heavy duty, 90° rght-angle lock, along with my 128db alarm all but guarantee would-be thieves will look for an easier target.CON -- Must be precise with key to un/lock. Otherwise, frustrating, especially in hot Florida sun with impending downpour and lightning.OVERALL -- AN AMAZING PRODUCT. HIGHLY RECOMMENDED.

The Best!!
A perfect size for my escooter. It fits securely from signpost to behind the front wheel where the scooter hinge is. I’ve never been able to lock the body before, only the neck. I’m thrilled! And there’s a reason this lock is 10 out of 10 — it is beautifully constructed, like a German car. Well worth the $ for the peace of mind.

Decent
It's a light and easy to carry lock if you're on the go. The size allows you to easily lock both the wheel and frame to a bike rack. However, be aware that criminals are brazen these days and carry portable angle grinders which will cut through this in minutes if not seconds. I highly recommend you use a 2nd and thicker, more angle-grinder resistant lock for added security.

INTIMIDATING
This baby ain't light weight, but it will depress a thief on site. It's reputation preceed it! I'm completely impressed and walk away from my bike with confidence. Anything less is just a target and a minor challenge.

Top security
Very secure lock. The key unlocking takes some wiggling of the key to get it to open. Hopefully that will get easier over time. I have a comfort level leaving the bike for a short time.

Needs a little engineering improvements.
The U-Lock heavy duty as indicated, I only hope the steel is properly hardened to ensure protection as needed.Disappointed in the quality of the lock mechanism itself as the Key is a fight everytime to get it in and out.The Cable included is extremely disappointing, very hard to use considering its stiffness in gards to its coil memory. Not really a useable product.

Qualitaet
Habe es seit langer Zeit nun und es haelt was es verspricht. Schloss geht immer noch. So schwer wie es ist scheint es auch massiver Stahl zu sein.Das Kabel hilft mir den zweiten Reifen mit anzuschliessen.

Ben realizzato e versatile
Di semplice utilizzo, sembra sufficientemente robusto da svolgere correttamente la sua funzione. Ho apprezzato la lunghezza del lucchetto, molto utile per mettere in sicurezza la bici, ma di contro difficile da posizionare per il trasporto. Soddisfatto dell'acquisto

Muy decepcionada/ Very dissapointed.
ES/ENPués pensaba que me compraba un gran candado, pero estoy decepcionadísima.1_ El soporte no lo aguanta, con lo que tengo que llevarlo en el bolso. Con lo que pesa!2_Las instrucciones son inútuiles en mi ipinión.3_Abrir y cerrar el candado es una odisea. Puedo estar minutos intentando ponerlo.Sinceramente, si lo sé, no lo hubiera comprado. Tengo que buscarme otro que pueda utiliar con facilidad.I am extremely disappointed1_ The support is not strong enough to carry the weight, so I cannot use it and have to carry it on the bad. And it is really heavy.2_The instructions are awful. I could not understand them.3_To open and close it is an odyssey. i can spend minutes and minutes trying to lock the bike.A total waste of money in my opinion. I need to buy a new one that i actually can use.

Sicher,aber schwer
Sehr gute Verarbeitung, massiv - daher natürlich entsprechend schwer.Dazu gibts mehrere Schlüssel und ein separates Sicherungskabel (Achtung, nicht so stabil wie das Schloß).Damit kann man Vorder u. Hinterrad mit abschließen oder sein Equipment schützen.Schloß ist natürlich mit Schutzhülle überzogen damit man sich sein Rad nicht beschädigt.

Hochwertiges Schloss
Das Schloss gefällt mir echt gut. Das Kabel könnte etwas dicker sein. Was mich stört, dass bei der Halterung zwei Schrauben nicht dabei sind.
