Effective lock but read the instructions carefully first!
I rate ABUS kit functional with reasonable quality. This is a great product for it's intended purpose - ie preventing opportunistic theft by securing your bike for a few mins in low risk environments. It's lightweight and compact so can fit in a jersey pocket with no hassle. Fight the temptation to fiddle with it straight out of the box as you could get locked out of your own lock! The instructions aren't the clearest, but if you follow them carefully for first usage, you can set your own code and operate the lock quite easily.

Useful security device
Works quite well, obviously not high security but works great as a deterrent. I purchased for securing skis when leaving unattended, for example when stopping at a busy mountain cafe or restaurant, or in an open ski room. Stops someone inadvertently taking the wrong skis by mistake, which occasionally does happen, a cheap and simple lightweight deterrent.

Security against the opportunistic thief
Good quality if a bit fiddly to use, worked a treat in a Eurotrain where luggage is nowhere near the seats

A simple to use, but low security deterrent
It’s a very compact, easy to carry and easy to use deterrent. It won’t put up much of a fight to bolt cutters, but it will stop someone simply walking off with my bike. It may even make someone think twice about wanting to steal my bike.

Lightweight and long enough to feed through several cases or rucksacks
Lightweight and long enough cable to feed through several cases or rucksacks. Useful for travelling by bus or train to secure your bags in the luggage rack.

good lock
good quality, easy to use. has all the functions that are important in these locks (its not just the locking and unlocking, but also the ability to lock the length of the chord - which this does, and a few other things)

Poor code setting instructions
Giving 3 stars based on lack of decent instructions for initial set up. Almost had it set to a random number due to poor instructions and set button releasing prematurely but thankfully worked it out. Better instructions please!! On a plus, seems nice & light for travelling with.

Good but not super secure.
Works ok, its made from plastic, so would not deter a determined thief. But its OK for securing the helmet to the motor bike, which is what I use it for occasionally

Ich habe mir das ABUS Combiflex Spezialschloss gekauft, um unterwegs eine schnelle und leichte Sicherungslösung für mein Fahrradhelm, meinen Rucksack oder mein Fahrrad in der Arbeit zu haben. Wichtig war mir vor allem ein Schloss, das handlich und unkompliziert ist, aber trotzdem zuverlässigen Schutz im Alltag bietet. Erster Eindruck / Verarbeitung: Das Schloss wirkt sofort hochwertig verarbeitet – wie man es von ABUS kennt. Das Gehäuse ist robust, die Zahlenräder lassen sich leichtgängig einstellen und rasten sauber ein. Das Kabel fährt federleicht ein und wieder aus, sodass es schnell einsatzbereit ist. Anwendung & Praxiserfahrung: Das Schloss ist sehr vielseitig nutzbar: • Zum kurzzeitigen Sichern von Taschen, Rucksäcken oder Helmen. • Perfekt für Reisen, da es klein genug ist, um in jede Tasche zu passen. • Auch beim Sport (z. B. Fitnessstudio oder Fußballtraining) praktisch, um Ausrüstung kurz anzuschließen. Natürlich ersetzt es kein massives Bügel- oder Kettenschloss – dafür ist es nicht gedacht. Aber für die schnelle Sicherung bietet es ein gutes Maß an Schutz und vor allem eine große Flexibilität. Vor- und Nachteile: ✅ Vorteile: • Sehr handlich und leicht, passt in jede Tasche bzw Trikottasche • Einfach zu bedienen (Zahlenkombination) • Hochwertige Verarbeitung, langlebig • Vielseitig einsetzbar (Helme, Taschen, Kinderwagen etc.) ❌ Nachteile: • Kein Ersatz für ein vollwertiges Fahrradschloss • Kabel könnte für manche Anwendungen etwas länger sein Fazit: Das ABUS Combiflex Spezialschloss ist die perfekte Lösung für alle, die unterwegs eine leichte und flexible Sicherung benötigen. Ob auf Reisen, beim Sport oder im Alltag – es bietet schnellen Schutz für Gepäck, Ausrüstung oder auch das Fahrrad und überzeugt durch Qualität und Handlichkeit. Für meine Zwecke absolut ideal.

Świetne kompaktowe zapięcie, które mogę mieć ze sobą na właściwie każdej przejażdżce. Oczywiście nie jest specjalnie mocne i pancerne ale do zostawienia roweru pod sklepem spokojnie się nadaje a mieści się w każdej kieszonce.
