Locks that work

Yes I was looking at the decathlon ones, hadnt realised it was a different model. I was originally leaning towards the on guard as it is rated as the 3rd best primary d on the first page whilst the abus only appears on the secondary list, any reason for choosing one over the other?

Onguards have a reputation for not being well (or at all) weatherproofed IIRC. FWIW I've got 2 Abus Mini 40s and they work very nicely. They certainly feel very solid. They are pretty small though: you're unlikely to get round a frame tube, wheel and bike stand unless you have mad tight clearances.
