Think very carefully. If you really do think the bikes are at risk then this is unlikey to help.
It’s only going to be as good as the padlock it’s locked with. Unless you are spending good money on a padlock then it’s no good. Bolt croppers go through cheap padlocks like cheese (or like a chain through a shimano chainring!). 5 locking points means 5x expensive padlocks.
If you do use an expensive padlock they’ll just pry it and tear the metal around the hasp (or cut the hasp as they are only cheap ones)
It is going to be great if you are in a low risk area, are unlikely to have people snooping around, but once they know it is there with bikes in it they’ll be in it with seconds if they want to be.
Good bolt croppers will go through the £60 Abus D locks like cheese.
I bought an Almax series 4 chain and squire strong hold padlock. Not cheap, but if the bikes really are ‘at risk’ then it is about your only chance. Look at the videos on their website if you don’t believe me about bolt croppers)
